2    
3            * test/support.py (ThubanTestResult.printErrors): Indent the
4            reason for the skips in the output to make it a bit more readable.
5            (execute_as_testsuite): New helper function to run a test suite
6            and print some more information.
7            (run_tests): Use execute_as_testsuite to run the tests
8    
9            * test/runtests.py (main): Use execute_as_testsuite to run the
10            tests
11    
12    2003-08-18  Bernhard Herzog  <[email protected]>
13    
14            Fix some bugs in Thuban and the test suite that were uncovered by
15            changes introduced in Python 2.3:
16    
17            * Thuban/Model/table.py (DBFTable.__init__): Make sure the
18            filename is an absolute name
19    
20            * Thuban/Model/layer.py (RasterLayer.__init__): Make sure the
21            filename is an absolute name
22    
23            * test/test_save.py (SaveSessionTest.testRasterLayer): Use a
24            unique filename to save to and use the correct relative filename
25            in the expected output.
26            (SaveSessionTest.test_dbf_table): Use the correct relative
27            filename in the expected output.
28    
29            * test/test_layer.py (TestLayer.test_raster_layer): Update the
30            test to check whether the filename is absolute.

35    
36    2003-08-15  Bernhard Herzog  <[email protected]>
37    
38            Change the way shapes are returned by a shape store. The

59            layer_shapes() change
60    
61            * Thuban/UI/renderer.py (ScreenRenderer.layer_ids)

101            to indicate whether the callable can deal with the raw shape data
102            or uses the higher level python lists of coordinates. The callable
103            now should accept either the raw data or the return value of the
104            shape's Points() method.
105            (BaseRenderer.draw_shape_layer): Adapt to the low_level_renderer
106            change

143            * test/test_layer.py (TestLayer.test_point_layer_with_projection):
144            New. Test coordinate handling of a layer with a projection.
145            Catches the bug fixed in Layer.ShapesInRegion

148    
149            Move some of the mock objects in test_baserenderer into their own
150            module so they can easily be used from other tests
151

175    
176            * test/support.py (FloatComparisonMixin.assertPointListEquals):
177            New. This method was used in various derived classes, but it's
178            better to have it here.
179    
180            * test/test_shapefilestore.py
181            (ShapefileStoreTests.assertPointListEquals): Removed. It's now in

221    2003-08-07  Bernhard Herzog  <[email protected]>
222    
223            * Thuban/Model/data.py (DerivedShapeStore.RawShapeFormat): New.
224            Simply delegates to the original shapestore.
225    
226            * test/test_derivedshapestore.py
227            (TestDerivedShapeStore.test_raw_format): New. Test case for
228            DerivedShapeStore.RawShapeFormat

232            Add raw data interface to shape objects.
233    
234            * Thuban/Model/data.py (ShapefileShape, Shape): Rname the shape
235            class to ShapefileShape which now holds shapefile specific
236            information.
237            (ShapefileShape.compute_bbox): Simplified to not cache any
238            information. The way this method is used that shouldn't matter
239            performance wise.

241            data format for shapes from shapefiles.
242            (ShapefileStore.RawShapeFormat): New. Return the raw datatype used
243            in the shape objects returned by a shapestore. For a
244            ShapefileStore this is always RAW_SHAPEFILE.
245            (RAW_PYTHON, RAW_SHAPEFILE): Constants for the RawShapeFormat
246            method.
247    
248            * test/test_shapefilestore.py
249            (TestShapefileStore.test_raw_format): New test to test the raw
250            format feature of shapes.
251    
252            * Thuban/Model/layer.py: Remove the unused import of Shape from
253            data. It was only there for interface compatibility but it's not
254            used inside of Thuban and the generic Shape class has gone away.
255    
256            * Thuban/UI/renderer.py (MapRenderer.low_level_renderer): Check
257            the raw data format and only use an optimized version of its a
258            shapefile.

261    
262            * test/test_baserenderer.py (SimpleShape): Shape class for the
263            tests.
264            (SimpleShapeStore.Shape): Use SimpleShape instead of
265            Thuban.Model.data.Shape to make the tests independed of the coming
266            changes.

268    2003-08-07  Bernhard Herzog  <[email protected]>
269    
270            * test/support.py (SkipTest, ThubanTestResult, ThubanTestRunner)
271            (ThubanTestProgram): New classes that extend the respective
272            classes from unittest. These new version support skipping tests
273            under certain expected conditions. In the Thuban test suite we
274            uses this for tests that require the optional gdal support.
275            (run_tests): Use ThubanTestProgram instead of the unittest.main()
276    
277            * test/runtests.py (main): Use the new ThubanTestRunner instead of
278            the normal one from unittest
279    
280            * test/test_layer.py (TestLayer.test_raster_layer): If this test
281            is not run because gdal support isn't available report this to the
282            runner.
283    
284            * test/test_baserenderer.py
285            (TestBaseRenderer.test_raster_no_projection): Do not run this test
286            if gdal support isn't available and report this to the runner.
287    
288    2003-08-06  Bernhard Herzog  <[email protected]>
289    
290            Rearrange the renderers a bit, partly in preparation for changes
291            required for the postgis merge, partly to make it more testable.
292            Also make the representation of coordinates in Shapes more
293            consistent.
294    
295            * Thuban/UI/renderer.py (MapRenderer): Most of the code/methods in
296            this class is now in BaseRenderer. This class is now practically
297            only a specialization of BaseRenderer for rendering to an actual
298            wx DC.
299            (ScreenRenderer.draw_shape_layer): Use self.low_level_renderer()
300            to get the shapetype specific rendering functions.
301    
302            * Thuban/UI/baserenderer.py: New file with the basic rendering
303            logic. The code in this file is completely independend of wx.
304            (BaseRenderer): Class with the basic rendering logic
305    
306            * test/test_baserenderer.py: New. Test cases for BaseRenderer
307    
308            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
309            error_on_redraw to guard agains endless loops and stack overflows
310            when there's a bug in the rendering code that raises exceptions.
311            (MapCanvas.OnIdle, MapCanvas._do_redraw): Split the actual
312            rendering into a separate method _do_redraw so that error handling
313            is a bit easier. When an exception occurs, set error_on_redraw to
314            true. When it's true on entry to OnIdle do nothing and return
315            immediately.
316    
317            * Thuban/Model/data.py (ShapefileStore.Shape): For consistency, a
318            Shape object will always have the coordinates as a list of list of
319            coordinate pairs (tuples).
320            (Shape.compute_bbox): Adapt to new representation.
321    
322            * Thuban/UI/viewport.py (ViewPort.find_shape_at)
323            (ViewPort.LabelShapeAt): Adapt to new coordinate representation in
324            Shape objects.

327            (ShapefileStoreTests.assertFloatTuplesEqual)
328            (ShapefileStoreTests.assertPointListEquals): Rename to
329            assertPointListEquals and change purpose to checking equality of
330            the lists returned by Shape.Points().

332            (TestShapefileStorePolygon.test_shape)
333            (TestShapefileStorePoint.test_shape): Use the new
334            assertPointListEquals instead of assertFloatTuplesEqual
335    
336            * test/test_layer.py (TestLayer.assertFloatTuplesEqual)
337            (TestLayer.assertPointListEquals): Rename to assertPointListEquals
338            and change purpose to checking equality of the lists returned by
339            Shape.Points().
340            (TestLayer.test_arc_layer, TestLayer.test_arc_layer)
341            (TestLayer.test_polygon_layer, TestLayer.test_point_layer)
342            (TestLayer.test_derived_store): Use the new assertPointListEquals
343            instead of assertFloatTuplesEqual
344    
345            * test/test_derivedshapestore.py
346            (TestDerivedShapeStore.assertFloatTuplesEqual)
347            (TestDerivedShapeStore.assertPointListEquals): Rename to
348            assertPointListEquals and change purpose to checking equality of
349            the lists returned by Shape.Points().
350            (TestDerivedShapeStore.test_shape): Use the new
351            assertPointListEquals instead of assertFloatTuplesEqual
352    
353    2003-08-06  Jan-Oliver Wagner <[email protected]>
354    
355            * Thuban/UI/projdialog.py (UTMPanel._OnPropose): Added test for
356            a bounding box. A dialog is raised in case, no bounding box
357            is found. This fixes bug #2043:
358            https://intevation.de/rt/webrt?serial_num=2043
359    
360    2003-08-05  Bernhard Herzog  <[email protected]>
361    
362            * Thuban/Model/color.py (Color.__repr__): Make the repr of a color
363            object look like a Color instantiation. Formerly it looked like a
364            tuple.
365    
366            * test/test_color.py (TestColor.test_repr)
367            (TestColor.test_equality, TestColor.test_inequality): New. test
368            some more apects of the Color class

371            Transparent object.
372    
373    2003-08-04  Jan-Oliver Wagner <[email protected]>
374    
375            * Doc/manual/thuban-manual.xml: a number of small improvements.
376            The resulting file is the version submitted for GREAT-ER II.
377    
378    2003-08-01  Bernhard Herzog  <[email protected]>
379    
380            * Thuban/UI/resource.py, Thuban/UI/projdialog.py,

385            (Color2wxColour, wxColour2Color, ThubanBeginBusyCursor)
386            (ThubanEndBusyCursor): Add doc-strings
387    
388    2003-08-01  Bernhard Herzog  <[email protected]>
389    
390            First step towards PostGIS integration. More abstraction by movin
391            more code from the layer to the shapestore. More methods of the
392            layer are now simply delegated to the equivalent method of the
393            shapestore. The SHAPETYPE_* constants are now in data not in
394            layer.
395    
396            * Thuban/Model/data.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
397            (SHAPETYPE_POINT, Shape): Move these constants and classes from

402            (ShapefileStore.BoundingBox, ShapefileStore.ShapesInRegion)
403            (ShapefileStore.Shape): New methods that were formerly implemented
404            in the layer.
405            (DerivedShapeStore.Shape, DerivedShapeStore.ShapesInRegion)
406            (DerivedShapeStore.ShapeType, DerivedShapeStore.NumShapes)
407            (DerivedShapeStore.BoundingBox): New. DerivedShapeStore
408            equivalents of the new shape methods. These versions are simply
409            delegated to the original shapstore.
410    
411            * Thuban/Model/layer.py (SHAPETYPE_POLYGON, SHAPETYPE_ARC)
412            (SHAPETYPE_POINT, Shape): Removed. They're now in data.py
413            (Layer.SetShapeStore): Removed the initializatin of instance
414            variables that were needed for the stuff that's now in
415            ShapefileStore
416            (Layer.BoundingBox, Layer.NumShapes, Layer.ShapeType)
417            (Layer.Shape, Layer.ShapesInRegion): Simply delegate to the
418            shapestore.
419    
420            * Thuban/UI/classifier.py, Thuban/UI/renderer.py,

422            instead of layer.
423    
424            * test/test_shapefilestore.py: New. Tests for ShapefileStore.
425

427    
428            * test/test_layer.py: Import the SHAPETYPE_* constants from data

431            when instantiating the DerivedShapeStore with an incompatible
432            table which is now in test_derivedshapestore.py. Add some more
433            tests of the layer methods to determine whether they work for a
434            DerivedShapeStore as well.
435    
436    2003-07-31  Jonathan Coles   <[email protected]>
437    
438            * Doc/manual/thuban-manual.xml: Fix the list of required packages
439            by just listing the name and where they can be found.
440    
441    2003-07-31  Frank Koormann   <[email protected]>
442    
443            * Doc/manual/thuban-manual.xml:
444            Changed the screenshot elements to figure.
445            Changed some variablelist elements to itemizedlist.
446            Added section on GDAL formats.
447    
448    2003-07-31  Jonathan Coles   <[email protected]>
449    
450            * Doc/manual/thuban-manual.xml: Added a few sentences about
451            the Fix Border Color option when generating classes.
452    
453    2003-07-30  Jonathan Coles   <[email protected]>
454    
455            * Thuban/Model/classgen.py: Add docstrings. Rename specific
456            Ramp instances to use lower_case_style.
457    
458            * Thuban/UI/classgen.py: Use renamed Ramp instances.
459            
460            * Thuban/UI/classifier.py: Add docstrings.

465    
466    2003-07-30  Bernhard Herzog  <[email protected]>
467    
468            * Thuban/Lib/connector.py (QueueingPublisher): Removed. This class
469            was never used in Thuban.
470    
471    2003-07-30  Bernhard Herzog  <[email protected]>
472    
473            * Thuban/UI/join.py (JoinDialog.__init__): Use the table's Title()
474            method directly instead of going through the transient_table
475            method. This faster because transient_table may force the copy of
476            a DBF file into the transient database and setting a table's title
477            doesnm't affect the title of the associated transient table, so
478            this fixes RT #2042
479    
480            * Thuban/UI/main.py (__version__): Don't import the already
481            removed show_exception_dialog.
482    
483    2003-07-29  Jonathan Coles   <[email protected]>
484    
485            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
486            Put back this method and remove the equivalent function since we
487            are setting the exception hook from within this class (OnInit).
488    
489    2003-07-29  Jonathan Coles   <[email protected]>

496    
497            * Doc/manual/thuban-manual.xml: Fixed typos and wording, clarified

502            * Thuban/Model/data.py: Remove the now unused import of warnings
503    
504    2003-07-29  Bernhard Herzog  <[email protected]>
505    
506            * Thuban/Model/data.py (SimpleStore): Removed. This class has been
507            deprecated since before the 0.8 release and isn't used in Thuban
508            itself anymore.
509    
510            * Thuban/Model/transientdb.py: Remove some unnecessary imports
511    
512    2003-07-29  Jonathan Coles   <[email protected]>
513    
514            * Thuban/UI/application.py (ThubanApplication.OnInit): set the
515            python exception hook here so that we are sure to catch any
516            Thuban exception that happen during initialization.
517    
518            * Thuban/UI/main.py (main): Don't set the exception hook here,
519            it will get set in ThubanApplication.OnInit.
520    
521    2003-07-29  Jonathan Coles   <[email protected]>
522                                                                                
523            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
524            Removed and called it show_exception_dialog() so that the exception
525            handler can be set before the class is created.
526                                                                                
527            * Thuban/UI/main.py (main): Install the exception handler before
528            a ThubanApplication is created.

584    2003-07-24  Bernhard Herzog  <[email protected]>
585    
586            * Thuban/Model/range.py, Thuban/version.py: Remove the #! line as
587            it annoys lintian which warns about these files not being
588            executable. The #1 isn't necessary here since if you absolutely
589            must execute them you can always say "python <filename>".
590    
591            * Thuban/UI/renderer.py (ScreenRenderer.draw_shape_layer): Remove
592            superfluous code to set brush and pen for point shapes

606    2003-07-22  Jonathan Coles   <[email protected]>
607    
608            * Doc/manual/thuban-manual.xml: Continue to write first revision
609            of the manual.
610    
611            * Thuban/UI/renderer.py (MapRenderer.render_map): Wrap method
612            with Begin/EndDrawing() calls to ensure we aren't doing to
613            many updates to the dc during rendering.
614            (ScreenRenderer.draw_shape_layer): self.draw_point_shape takes
615            a pen and brush argument so they need to be passed to the function.
616    
617            * Thuban/UI/viewport.py (ViewPort.calc_min_max_scales): New.
618            Calculates the minimum and maximum scale values. Factored out
619            of set_view_transform so that it could be used to zoom all the
620            way into a single point.
621            (ViewPort.set_view_transform): Call calc_min_max_scales().
622            (ViewPort.FitSelectedToWindow): Zoom to the maximum scale
623            if only a single point is selected.

658            prepare_new_session has been removed.
659

676            Move this test from ViewPortTest.setUp to this new separate test
677            case. setUp is not the place for the actual tests.
678            (ViewPortTest.test_inital_settings, ViewPortTest.setUp): Move some
679            more of the test from setUp to the new test test_inital_settings.

697            connection. To make sure this remains true, remove the DISPLAY
698            environment variable so that an error occurs if the wxGTK is
699            imported accidentally

722            Rename to output_transform
723    
724    2003-07-18  Bernhard Herzog  <[email protected]>
725    
726            * Thuban/Model/layer.py (Layer.__init__): Rename
727            classificationField to classificatin_column and init it here so
728            that it can be used in SetClassificationColumn

769    2003-07-18  Bernhard Herzog  <[email protected]>
770    
771            * test/test_classgen.py (TestFixedRamp.test): Extend test to check
772            the non-fixed values as well. The old test would have accepted a
773            fixed ramp that only returnes the fixed properties
774    
775    2003-07-17  Jonathan Coles   <[email protected]>
776    
777            * Doc/manual/mainwindow.png, Doc/manual/mainwindow.xcf: Screen
778            shots for the manual. The XCF file is the source image and
779            has additional layers to support changes.
780    
781            * Doc/manual/thuban-manual.xml: Wrote an initial Introduction.
782    
783            * Thuban/UI/classifier.py (Classifier.__BuildClassification):
784            Return both the new class and the field name.
785    
786            * Thuban/UI/mainwindow.py (MainWindow.ToggleLegend): Don't
787            fit the map to the window as this changes any zoom level that
788            the user may have set.
789    
790    2003-07-16  Jonathan Coles   <[email protected]>
791    
792            * Thuban/Model/classgen.py (generate_singletons,
793            generate_uniform_distribution, generate_quantiles): Remove
794            fixes parameter, but maintain the same functionality by having
795            the calling function pass a FixedRamp object for the ramp.
796            (FixedRamp): New. Adapts a ramp to have fixed property values.
797    
798            * Thuban/Model/classification.py: Use new CLASS_CHANGED message.
799            (Classification): Inherit from Publisher.
800            (Classification.__init__): Remove the layer parameter.
801            Classifications no longer need to have a parent layer.
802            (Classification.GetField, Classification.GetFieldType,
803            Classification.SetFieldInfo): Removed. The field name is stored
804            in the layer, and the type can be retreived by calling
805            Layer.GetFieldType().
806            (Classification._set_layer, Classification.GetLayer): Removed.
807            Classifications no longer have a parent layer.
808    
809            * Thuban/Model/layer.py (Layer.Destroy): Unsubscribe from the
810            classification.
811            (Layer.SetShapeStore): Reset the classification first while
812            we still have the old shape store to work with.
813            (Layer.GetClassificationField, Layer.SetClassificationField):
814            New. Method for getting/setting the field to classify on.
815            (Layer.SetClassification): Simplified now that the layer
816            simply has to hold a reference to the classification and not
817            tell the classification who owns it.
818            Fixes RTbug #2023.
819    
820            * Thuban/Model/load.py (SessionLoader.start_classification):
821            Set the field name on the layer, not the classification.
822    
823            * Thuban/Model/messages.py: Add CLASS_CHANGED for when a
824            classification is modified.
825    
826            * Thuban/Model/save.py (SessionSaver.write_classification):
827            Get the field name and type from the layer.
828    
829            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Renamed
830            parameter records to rows and add docstring. Fixes RTbug #1997.
831    
832            * Thuban/UI/classgen.py (ClassGenDialog.OnOK): Use a fixed
833            ramp when we need to fix certain values of a ramp rather than
834            using the old fixes parameter. Fixes RTbug #2024.
835    
836            * Thuban/UI/classifier.py (ClassGrid.CreateTable): Add fieldType
837            parameter.
838            (ClassTable.Reset): Add fieldType parameter and use it, rather
839            than asking the classification.
840            (Classifier.__init__): Remember the original class's field
841            and ask the layer for the field type, rather than the classification.
842            (Classifier.__SetGridTable): Retrieve the field and field type
843            for the table because they are not in the classification.
844            (Classifier._OnTry, Classifier._OnRevert): Set the classification
845            field on the layer in addition to the classification itself.
846    
847            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Get the
848            classification field from layer.
849    
850            * Thuban/UI/viewport.py (ViewPort.find_shape_at): Get the
851            classification field from layer. Split up tests and remove
852            *-imports. Fixes RTbug #1992.

854            * test/test_classgen.py (TestFixedRamp): Test for the FixedRamp class.
855    
856            * test/test_classification.py
857            (TestClassification.test_classification): Remove tests for methods
858            that no longer exist.
859    
860            * test/test_layer.py (SetShapeStoreTests.setUp): Classification
861            __init__ no longer has a field parameter, use SetClassificationField.
862            (SetShapeStoreTests.test_sanity): Use layer object to get class
863            field info.
864    
865            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Use
866            SetClassificationField on layer to set class field info.
867    
868            * test/test_viewport.py: Renamed from test/test_view.py.
869    
870    2003-07-16  Jan-Oliver Wagner <[email protected]>
871    
872            * Doc/manual/thuban-manual.xml: Added authors and an initial
873            coarse structure.
874    
875    2003-07-15  Bernhard Herzog  <[email protected]>
876    
877            * test/support.py (FloatComparisonMixin): This is a mix-in class
878            and therefore should not be derived from any other class.
879    
880            * test/test_range.py (RangeTest): FloatComparisonMixin is a
881            mix-in, so derive from TestCase as well.
882    
883    2003-07-15  Bernhard Herzog  <[email protected]>
884    
885            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Rework the
886            draw_func handling a bit to remove one layer of indirection. This
887            makes the renderer about 10% faster in the non-classifying case
888            and the code a bit cleaner
889            (MapRenderer.draw_point_shape): Add the pen and brush parameters
890            and set them in the dc. Now the draw_point_shape method and
891            wxproj's draw_polygon_shape function have basically the same
892            signature so that both can be directly used as draw_func
893    
894    2003-07-15  Bernhard Herzog  <[email protected]>
895    
896            * Thuban/Model/save.py (SessionSaver.write_classification): Encode
897            string values (in addition to the labels) as UTF 8
898    
899            * Thuban/Model/load.py (SessionLoader.start_clpoint): Decode the
900            values if the field type is string
901    
902            * test/test_save.py (SaveSessionTest.testClassifiedLayer): Test
903            saving a session with non-ascii string classification values.
904    
905            * test/test_load.py (TestClassification.file_contents)
906            (TestClassification.test): Check for non-ascii values in string
907            classifications
908    
909    2003-07-14  Jonathan Coles   <[email protected]>
910    
911            * test/test_view.py: New. Tests for ViewPort.
912    
913    2003-07-14  Frank Koormann   <[email protected]>
914    
915            * Thuban/Model/load.py (SessionLoader.start_map): Encode map
916            title to latin1.  Fixes https://intevation.de/rt/webrt?serial_num=2013

922    2003-07-10  Jonathan Coles   <[email protected]>
923    
924            * Thuban/UI/viewport.py (Tool.MouseUp): Should have called
925            drag_stop, not drag_move when the mouse is released.
926    
927    2003-07-10  Jonathan Coles   <[email protected]>
928    
929            The most important part of this is the seperation of view.py into
930            two pieces. viewport.py now has a class called ViewPort which
931            contains all the non-wx parts of view.py and can therefore be
932            tested. view.py contains only the wx-specific parts and is fairly
933            simple.
934    
935            * Thuban/UI/view.py: Stripped out all non-wx functionality. Fixes
936            RTTbug #1992.
937            * Thuban/UI/viewport.py: New. Contains non-wx view functionality.
938            RTTbug #1992.

940            * Thuban/Model/classgen.py (generate_singletons,
941            generate_uniform_distribution, generate_quantiles):
942            Added 'fixes' parameter so that property attributes can
943            be held constant over the generated classification groups.
944            (CustomRamp.GetProperties): Remove unused variables.
945    
946            * Thuban/Model/map.py (Map.SetProjection): Send the old
947            projection as an argument to listeners of the MAP_PROJECTION_CHANGED
948            event.
949    
950            * Thuban/Model/table.py (table_to_dbf, table_to_csv): Added 'records'
951            parameter which is a list of records that restricts which
952            records are saved. Fixes RTbug #1997.
953    
954            * Thuban/UI/application.py (ThubanApplication.ShowExceptionDialog):
955            Port exception dialog from GREAT-ER. Fixes RTbug #1993.
956    
957            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Add controls
958            to allow the user to fix line color/width on generated groups.

960            functions to optionally fix group properties.
961    
962            * Thuban/UI/main.py (main): Set exception hook to the

969            Export Selection button and move the export buttons underneath
970            the table.
971            (QueryTableFrame.UpdateStatusText): Added event argument so
972            that it can respond to grid selection events. The status text
973            is now updated even when the table is not associated with a
974            layer as was previously assumed.
975            (QueryTableFrame.OnGridSelectRange, OnGridSelectCell): Removed.
976            UpdateStatusText responds to these events.
977            (QueryTableFrame.OnSaveAs): Renamed to doExport.
978            (QueryTableFrame.doExport): Helper function that saves the
979            entire table, or selected rows, to a file.

982    
983            * extensions/thuban/gdalwarp.cpp (ProjectRasterFile): Make sure
984            the function doesn't return NULL without first setting a Python
985            Error.
986    
987            * test/runtests.py (main): Only print "Unknown option" for
988            unsupported options.

994    
995            * test/test_csv_table.py (TestCSVTable.test_table_to_cvs): Add
996            tests for saving selected records.
997    
998            * test/test_dbf_table.py (TestTableToDBF.test_table_to_dbf): Add
999            tests for saving selected records.
1000    
1001            * test/test_map.py (TestMapWithContents.test_set_projection):
1002            MAP_PROJECTION_CHANGED events send the old projection.
1003

1008            * test/test_table.py (TableTest): Update tests to use non-deprecated
1009            functions.
1010    
1011    2003-07-08  Bernhard Herzog  <[email protected]>
1012    
1013            * Thuban/Model/transientdb.py (TransientTableBase.Width): The type
1014            constants in the column objects are the standard ones defined in
1015            the table module.
1016    
1017            * test/test_transientdb.py
1018            (TestTransientTable.test_transienttable_to_dbf): New. Test whether
1019            exporting transient tables as DBF works. This should catch the bug
1020            just fixed in TransientTableBase.Width.
1021    
1022    2003-07-08  Bernhard Herzog  <[email protected]>
1023    
1024            * Thuban/Model/classgen.py (CustomRamp.GetProperties): Compute the
1025            interpolated colors correctly.
1026    
1027            * test/test_classgen.py (TestCustomRamp.test_color_interpolation):
1028            New. Test case for the fix in classgen.py
1029    
1030    2003-07-08  Bernhard Herzog  <[email protected]>

1094            * Doc/manual/thuban-manual.xml, Doc/manual/README: New. Skeleton
1095            for the Thuban manual and README with some basic information about
1096            the manual
1097    
1098    2003-07-03  Bernhard Herzog  <[email protected]>

1101            Update doc-string
1102            (TransientJoinedTable.create): Do not modify the column objects of

1130    
1131            * Thuban/Model/classgen.py (generate_singletons,
1132            generate_uniform_distribution, generate_quantiles,
1133            GenQuantiles0): The denominator was one to high when
1134            calculating the index for the ramp causing the index
1135            to never to reach one.
1136    
1137    2003-07-02  Jonathan Coles   <[email protected]>
1138    
1139            Changed the singature of ClassGroupRange.__init__ and
1140            ClassGroupRange.SetRange() so that the min/max values are
1141            passed as a tuple. This makes a better calling scheme for
1142            when a Range object is passed instead.
1143    
1144            * Thuban/Model/classgen.py: Fixed parameters to
1145            ClassGroupRange constructor.
1146

1157            the classification instance variable to the new class
1158            before calling _set_layer otherwise subscribers to a
1159            LAYER_CHANGED event will not see any difference.
1160    
1161            * test/test_classification.py: Fix tests of ClassGroupRange
1162            so that they use the new signature.
1163    
1164            * test/test_load.py: Fix use of ClassGroupRange so that it
1165            uses the new signature.
1166    
1167            * test/test_load_0_2.py: Fix use of ClassGroupRange so that it
1168            uses the new signature.
1169    
1170            * test/test_save.py: Fix use of ClassGroupRange so that it
1171            uses the new signature.

1174    2003-07-01  Jonathan Coles   <[email protected]>
1175    
1176            * Thuban/Model/classgen.py: Fixes RTbug #1972, 1971.
1177            Import used objects/class from color.
1178            (generate_singletons): We don't
1179            need the numGroups parameter anymore because we are using
1180            the new ramps with GetProperties().
1181            (generate_uniform_distribution): Use new ramp method
1182            GetProperties().
1183            (generate_quantiles, GenQuantiles0): Use new ramp method
1184            GetProperties().
1185            (CustomRamp.SetNumGroups): Removed. The ramps now map
1186            a value from 0 to 1 to class properties so the number
1187            of groups is not needed ahead of time.
1188            (CustomRamp.next): Removed. CustomRamp does not support
1189            interation anymore.
1190            (CustomRamp.GetProperties): Returns a ClassGroupProperties
1191            object based on the index value from 0 to 1 that is
1192            passed to it.
1193            (GreyRamp, RedRamp, GreenRamp, BlueRamp, GreenToRedRamp):
1194            Made into instances of Monochromatic class instread of
1195            deriving from it.
1196            (HotToCold.SetNumGroups): Removed. See CustomRamp.
1197            (HotToCold.next): Removed. See CustomRamp.
1198    
1199            * Thuban/Model/classification.py: Fixes RTbug #1973, 1971.
1200            (Classification.SetField, Classification.SetFieldType):
1201            Replaced with SetFieldInfo.
1202            (Classification.SetFieldInfo): New. Does a better job of
1203            what SetField and SetFieldType used to do by combining
1204            their function since they should really always be done
1205            at the same time.
1206            (Classification.SetLayer): Renamed to _set_layer.
1207            (Classification._set_layer): Should only be called from
1208            Layer's SetClassification. This does not cause a recursive
1209            call as SetLayer did because we know that Layer knows about
1210            the classification.
1211    
1212            * Thuban/Model/color.py: Fixes RTbug #1971.
1213            (_Transparent): Renamed from Transparent so it doesn't
1214            conflict with the module variable.
1215            (Transparent, Black): Renamed from Color.Transparent,
1216            Color.Black so they are not class variables.
1217    
1218            * Thuban/Model/layer.py: Fixes RTbug #1971, 1973.
1219            (Layer.Destroy): We don't need to call SetClassification
1220            anymore to clear out the back reference in the classifcation
1221            to the layer. It's better to set it to None using _set_layer,
1222            and we won't be creating another clas object too.
1223            (Layer.SetClassification): Classification._set_layer is not
1224            recursive so remove all the locking variables. Also clean
1225            up the code so that it remains unchanged if something fails.
1226    
1227            * Thuban/Model/load.py: Fixes RTbug #1971.
1228            (SessionLoader.start_classification): Call
1229            Classification.SetFieldInfo().
1230    
1231            * Thuban/Model/save.py: Removed import of Color which wasn't
1232            being used.
1233    
1234            * Thuban/UI/classgen.py: Fixes RTbug #1972.
1235            (ClassGenDialog.__init__): Color ramps are now instances
1236            already so we don't need to create any new objects.
1237            (ClassGenDialog.OnOK): Check for numGroups is no longer
1238            necessary because we never use it.
1239    
1240            * Thuban/UI/classifier.py: Fixes RTbug #1971.
1241            (Classifier.__BuildClassification, Classifier.__SetGridTable):
1242            Call Classification.SetFieldInfo() instead of SetFieldType.
1243    
1244            * Thuban/UI/renderer.py: Fixes RTbug #1971.
1245    
1246            * Thuban/UI/view.py: Fixes RTbug #1974, 1971.
1247            (MapCanvas.__init__): Subscribe to the idle time event. Set
1248            background color to white.
1249            (MapCanvas.OnPaint): Set a flag indicating that we should
1250            render the map during idle time. If we already have a bitmap
1251            just draw it now.
1252            (MapCanvas.OnIdle): New. Render the map only during idle time.
1253            This also fixes a problem with the busy cursor under gtk.
1254    
1255            * test/test_classgen.py (ClassGenTest.test_generate_singletons):
1256            Fix calls to generate_singletons because the signature changed.
1257    
1258            * test/test_classification.py: Fix color references and
1259            change calls to Classification.[SetField|SetFieldType] to
1260            SetFieldInfo.
1261    
1262            * test/test_load.py: Fix color references.
1263    
1264            * test/test_load_0_2.py: Fix color references.
1265    
1266            * test/test_save.py (SaveSessionTest.testClassifiedLayer):
1267            Change calls to Classification.[SetField|SetFieldType] to
1268            SetFieldInfo.
1269    
1270    2003-07-01  Frank Koormann   <[email protected]>
1271    
1272            MERGE from the greater-ms3 branch.
1273    
1274            * test/test_transientdb.py
1275            (TestTransientTable.test_transient_joined_table_with_equal_column_names):
1276            New. Test join of two tables with partly equal column names.
1277    
1278            * Thuban/Model/transientdb.py (TransientJoinedTable.create):
1279            If duplicates in left and right tables column names are found,
1280            append '_' (underscores) to the name until it is unique.
1281            Create always new internal names for the resulting table and reference
1282            columns in the join statement with <table>.<column>
1283    
1284    2003-07-01  Bernhard Herzog  <[email protected]>
1285    
1286            * test/test_transientdb.py
1287            (TestTransientTable.test_transient_joined_table_same_column_name):
1288            New. Test whether joining on columns with the same names in both
1289            tables works.
1290            
1291            * Thuban/Model/transientdb.py (TransientJoinedTable.create): Make
1292            sure to use the right internal names even when joining on field
1293            with the same names in both tables. Also, detect duplicate names
1294            in the joined table correctly.
1295    
1296    2003-07-01  Frank Koormann   <[email protected]>
1297    
1298            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
1299            Reverse List of layers to render in same order as in desktop legend.
1300    
1301    2003-06-30  Jonathan Coles   <[email protected]>
1302    
1303            * Thuban/version.py (make_tuple): Takes a version string
1304            and splits it into a tuple of at most three integers.
1305            Used make_tuple() to make tuple versions of the version
1306            numbers.
1307    
1308            * Thuban/UI/about.py: Add Thuban email addresses.
1309    
1310    2003-06-30  Jonathan Coles   <[email protected]>
1311    
1312            * Thuban/version.py: SQLite/PySQLite version dependencies
1313            were too high.
1314    
1315    2003-06-30  Jonathan Coles   <[email protected]>
1316    
1317            * Thuban/version.py: Update version to 0.8.1
1318            
1319            * MANIFEST.in: Added Projections so that default.proj is
1320            included.
1321    
1322    2003-06-26  Jonathan Coles   <[email protected]>
1323    
1324            New About box with lots more information including library
1325            versions and credits. More/better version checking before
1326            Thuban starts.
1327    
1328            * Thuban/UI/about.py: New. New About box that displays
1329            library version information and credits.
1330    
1331            * Thuban/version.py: Added new 'versions' dictionary which
1332            contains the verions of various libraries which are checked
1333            when the module loads.
1334            (verify_versions): Check all version numbers and returns
1335            a list of errors.
1336    
1337            * Thuban/UI/classifier.py (Classifier.__EnableButtons):
1338            Reset the status of the buttons as the situation warrants,
1339            but in a better more reliable way by not relying on the
1340            current status to determine what needs to change.
1341    
1342            * Thuban/UI/main.py (wxCHECK_VERSION): Removed. Not needed.
1343            (verify_versions): Remove most of the code since it is
1344            now in Thuban.version.verify_versions.o
1345    
1346            * Thuban/UI/mainwindow.py (MainWindow.About): Call new
1347            About box in Thuban.UI.about.
1348    
1349            * extensions/thuban/gdalwarp.cpp (get_gdal_version): New.

1357            was compiled with.
1358    
1359    2003-06-25  Jonathan Coles   <[email protected]>
1360    
1361            * Thuban/UI/classifier.py (Classifier.EditSymbol): The parent
1362            of the SelectPropertiesDialog should be self so the window
1363            appears on top.
1364            (ClassGroupPropertiesCtrl.DoEdit): The parent
1365            of the SelectPropertiesDialog should be self so the window
1366            appears on top.
1367    
1368            * Thuban/UI/resource.py: Cleaned up how we determine file
1369            extensions.
1370            (GetImageResource): Return an wxImage from our Resources.
1371    
1372    2003-06-24  Jonathan Coles   <[email protected]>
1373    
1374            * Thuban/UI/renderer.py (ExportRenderer.render_legend):
1375            Check that a layer has a classification before trying
1376            to get it. Raster layers don't have classifications.
1377    
1378    2003-06-23  Jonathan Coles   <[email protected]>
1379            
1380            * setup.py: Add Resources/XML to resource list.
1381        
1382    2003-06-23  Jonathan Coles   <[email protected]>
1383    
1384            * setup.cfg: Fix copyright dates
1385        
1386    2003-06-23  Jonathan Coles   <[email protected]>
1387    
1388            * MANIFEST.in: Update with Resources/XML
1389    
1390            * setup.py: Don't include Locale resources yet as we don't
1391            have any and it causes problems building the distribution
1392            for Windows. Update version to 0.8.0.
1393    
1394            * Doc/thuban.dtd: Removed since it is now in Resources/XML.
1395    
1396            * Thuban/UI/mainwindow.py: Add blank line at the end because
1397            file was not being read correctly building the Windows
1398            distribution.
1399    
1400    2003-06-23  Jonathan Coles   <[email protected]>
1401    
1402            * Thuban/UI/mainwindow.py (MainWindow.About): Fix text.
1403    
1404            * Thuban/version.py: Temporarily update longversion for

1406    
1407    2003-06-23  Jonathan Coles   <[email protected]>
1408    
1409            * Thuban/UI/common.py (ThubanBeginBusyCursor): Call wxSafeYield
1410            to make sure that we don't create reentrant possibilities with
1411            wxYield.
1412    
1413            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxBeginBusyCursor()
1414            directly to avoid the wxSafeYield() call which generates an
1415            OnPaint event causing infinite recursion. Don't try to catch
1416            exception anymore. This was for before there were limits on map
1417            scaling.
1418    
1419    2003-06-23  Bernhard Herzog  <[email protected]>
1420    
1421            Bug fix for RT #1961:
1422    
1423            * Thuban/Model/load.py (SessionLoader.start_derivedshapesource):
1424            Register DerivedShapestores with the session
1425    
1426            * Thuban/Model/session.py (Session.Tables): Make sure each table
1427            is only listed once.
1428    
1429            * test/test_load.py (TestJoinedTable.test): Add check_format call.
1430            Update file contents to match the one written out.
1431    
1432    2003-06-20  Bernhard Herzog  <[email protected]>
1433    
1434            * test/xmlsupport.py (SaxEventLister.startElementNS)
1435            (SaxEventLister.endElementNS): Do not include the qname. Python
1436            2.2.1 and 2.2.2 and 2.2.3 differ in this regard. In 2.2.1 qname it
1437            is (presumably incorrectly) None, whereas it's a string with the
1438            element name in the later versions.
1439    
1440            * test/test_xmlsupport.py (TestEventList.test_even_list_simple)
1441            (TestEventList.test_even_list_namespace): Update tests to reflect
1442            the new behaviour
1443            (TestEventList.test_even_list_id_normalization): Fix doc-string
1444    
1445    2003-06-20  Jonathan Coles   <[email protected]>
1446    
1447            * Thuban/Model/layer.py (BaseLayer.HasShapes): New. Overridden
1448            by deriving classes to determine if that layer supports shapes.
1449            (Layer): Override HasShapes and return true.
1450    
1451            * Thuban/UI/classgen.py: Use Thuban[Begin|End]BusyCursor()
1452            instead of a direct call to wx[Begin|End]CusyCursor().
1453            (GenUniquePanel._OnRetrieve): Set busy cursor while retrieving
1454            table data.
1455    
1456            * Thuban/UI/common.py (ThubanBeginBusyCursor, ThubanEndBusyCursor):
1457            New. Wrappers around the wxWindows functions that allow us to
1458            make additional calls such as wxYield which gives the native
1459            system a chance to update the cursor correctly.
1460    
1461            * Thuban/UI/tableview.py: Use Thuban[Begin|End]BusyCursor()
1462            instead of a direct call to wx[Begin|End]CusyCursor().
1463    
1464            * Thuban/UI/view.py: Use Thuban[Begin|End]BusyCursor()
1465            instead of a direct call to wx[Begin|End]CusyCursor().
1466            (MapCanvas.find_shape_at): Check if the current search layer
1467            support shapes, otherwise go on to the next layer.
1468    
1469            * test/test_layer.py: Add tests in each type of layer for
1470            HasClassification() and HasShapes()
1471    
1472    2003-06-20  Jonathan Coles   <[email protected]>
1473    
1474            * Thuban/UI/view.py (MapCanvas.OnPaint): Call wxYield after
1475            turning on the busy cursor to allow the system to change the
1476            cursor before we begin painting. This fixes a problem that
1477            was occuring only under GTK. Fixes RTbug #1840.
1478    
1479    2003-06-20  Bernhard Herzog  <[email protected]>
1480    
1481            * Resources/XML/thuban-0.8.dtd: New DTD for the new file format
1482            version.
1483    
1484            * Thuban/Model/save.py (sort_data_stores): New. Make topological
1485            sort of the data sources so they can be written with sources that
1486            data sources that depend on other data sources come after the
1487            sources they depend on.
1488            (SessionSaver.__init__): Add idmap instance variable to map from
1489            objects to the ids used in the file.
1490            (SessionSaver.get_id, SessionSaver.define_id)
1491            (SessionSaver.has_id): New. Methods to manage the idmap
1492            (SessionSaver.write): Use thuban-0.8.dtd
1493            (SessionSaver.write_session): Add a namespace on the session and
1494            write out the data sources before the maps.
1495            (SessionSaver.write_data_containers): New. Write the data
1496            containers.
1497            (SessionSaver.write_layer): Layer elements now refer to a
1498            shapestore and don't contain filenames anymore.
1499    
1500            * Thuban/Model/load.py (LoadError): Exception class to raise when
1501            errors in the files are discovered
1502            (SessionLoader.__init__): Define dispatchers for elements with a
1503            thuban-0.8 namespace too.
1504            (SessionLoader.check_attrs): New helper method to check and
1505            convert attributes
1506            (AttrDesc): New. Helper class for SessionLoader.check_attrs
1507            (SessionLoader.start_fileshapesource)
1508            (SessionLoader.start_derivedshapesource)
1509            (SessionLoader.start_filetable, SessionLoader.start_jointable):
1510            Handlers for the new elements in the new fileformat
1511            (SessionLoader.start_layer): Handle the shapestore attribute in
1512            addition to filename.
1513            (SessionLoader.start_table, SessionLoader.end_table): Removed.
1514            They were never used in the old formats and aren't needed for the
1515            new.
1516    
1517            * Thuban/Model/session.py (Session.DataContainers): New method to
1518            return all "data containers", i.e. shapestores and tables
1519    
1520            * test/xmlsupport.py (SaxEventLister.__init__)
1521            (SaxEventLister.startElementNS, sax_eventlist): Add support to
1522            normalize IDs.
1523    
1524            * test/test_xmlsupport.py
1525            (TestEventList.test_even_list_id_normalization): New test case for
1526            id normalization
1527    
1528            * test/test_load.py (LoadSessionTest.check_format): Use ID
1529            normalization
1530            (LoadSessionTest.thubanids, LoadSessionTest.thubanidrefs): New
1531            class atrributes used for ID normalization

1535            (TestJoinedTable): New test for loading sessions with joined
1536            tables.
1537            (TestLoadError): New. Test whether missing required attributes
1538            cause a LoadError.
1539    
1540            * test/test_save.py (SaveSessionTest.thubanids)
1541            (SaveSessionTest.thubanidrefs): New class attributes for ID
1542            normalization in .thuban files.

1546            (SaveSessionTest.testRasterLayer)
1547            (SaveSessionTest.testClassifiedLayer): Adapt to new file format.
1548            (SaveSessionTest.testLayerProjection): The filename used was the
1549            same as for testSingleLayer. Use a different one.
1550            (SaveSessionTest.test_dbf_table)
1551            (SaveSessionTest.test_joined_table): New test cases for saving the
1552            new data sources structures.
1553            (TestStoreSort, MockDataStore): Classes to test the sorting of the
1554            data stores for writing.
1555    
1556            * test/runtests.py: Add CVS keywords
1557    
1558    2003-06-20  Jonathan Coles   <[email protected]>
1559    
1560            * test/test_session.py
1561            (UnreferencedTablesTests.test_unreferenced_tables_with_joins):
1562            Use the cultural_landmark-point.dbf file for the store so that
1563            the table rows and shape count match.
1564    
1565    2003-06-20  Jonathan Coles   <[email protected]>
1566    
1567            * Thuban/Model/data.py (DerivedShapeStore.__init__): Raise
1568            an exception if the number of shapes is different from the
1569            number of rows in the table. Address RTbug #1933.
1570    
1571            * test/test_layer.py (TestLayer.test_derived_store): Add
1572            a test for the new exception in DerivedShapeStore.__init__.
1573    
1574            * test/support.py (FloatTestCase): Removed since there is
1575            already FloatComparisonMixin. Fixes RTbug #1954.
1576            (FloatComparisonMixin.assertFloatEqual): Include test for
1577            infinity that was part of FloatTestCase.
1578    
1579            * test/test_range.py (RangeTest): Inherit from
1580            support.FloatComparisonMixin now that we don't have
1581            support.FloatTestCase.
1582    
1583    2003-06-20  Bernhard Herzog  <[email protected]>
1584    
1585            * test/test_save.py (SaxEventLister, sax_eventlist): Removed. Use
1586            the implementation in xmlsupport instead.
1587            (SaveSessionTest.compare_xml): sax_eventlist is now in xmlsupport
1588    
1589            * test/test_proj.py: Import sax_eventlist from xmlsupport instead
1590            of test_save
1591    
1592    2003-06-20  Bernhard Herzog  <[email protected]>
1593    
1594            * test/test_load.py (LoadSessionTest.check_format): New helper
1595            method to make sure the test files we load might have been written
1596            by the current thuban version.
1597            (ClassificationTest.TestLayers, TestSingleLayer.test)
1598            (TestLayerVisibility.test, TestClassification.test)
1599            (TestLabels.test, TestLayerProjection.test, TestRasterLayer.test):
1600            Add check_format() calls and fix the thuban data to match the data
1601            that would be written by saving the session loaded from it.
1602    
1603            * test/xmlsupport.py (SaxEventLister, sax_eventlist): Copies of
1604            the same class and function in test_save.
1605    
1606            * test/test_xmlsupport.py (TestEventList): New. test cases for
1607            sax_eventlist
1608    
1609    2003-06-20  Bernhard Herzog  <[email protected]>
1610    
1611            * Resources/XML/thuban.dtd: Add comment about which versions of
1612            Thuban are covered by this DTD
1613            (map): Fix content model for layers and raster layers. There can
1614            be any number or layers and raster layers in any order.
1615    
1616    2003-06-20  Jonathan Coles   <[email protected]>
1617    
1618            This is mainly about fixing RTbug #1949.
1619    
1620            * Thuban/Model/classification.py: Remove "from __future__"
1621            import statement since python 2.2 is the earliest supported
1622            version.
1623    
1624            * Thuban/Model/proj.py (Projection.GetProjectedUnits): New.
1625            Currently returns PROJ_UNITS_METERS or PROJ_UNITS_DEGREES
1626            depending on the units this projection *forwards* into.
1627    
1628            * Thuban/Model/save.py (SessionSaver.write_classification):
1629            Remove unnecessary use of lambdas and nested functions.
1630    
1631            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Do scale
1632            adjustment here if the map projection uses degrees.
1633    
1634            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Remove
1635            scale adjust code since it is now done before calling
1636            this method. Don't do anything if the map projection
1637            is None.
1638    
1639    2003-06-19  Bernhard Herzog  <[email protected]>
1640    
1641            Move version specific load tests to their own file.
1642    
1643            * test/test_load.py: Expand the doc-string to explain a bit how to
1644            handle file format changes.
1645            (TestClassification.test): Update the docstring as this test is
1646            not about Thuban 0.2 anymore.
1647    
1648            * test/test_load_0_2.py: New file with the load tests for thuban
1649            files created with Thuban 0.2 and earlier.
1650    
1651    2003-06-19  Bernhard Herzog  <[email protected]>
1652    
1653            Add XML validation to some of the tests. Validation will only be
1654            done if pyRXP is installed (http://reportlab.com/xml/pyrxp.html).
1655            To make the DTD available to the test cases it's moved into
1656            Resources/XML
1657    
1658            * Resources/XML/thuban.dtd: New. This is now the real Thuban DTD
1659            for versions up to and including 0.2. Two slight changes: added an
1660            encoding specification and fixed the comment which refered to
1661            GRASS, not Thuban
1662    
1663            * test/xmlsupport.py: New support module for tests involving XML.
1664            Currently there's a mix-in class for XML validation.
1665    
1666            * test/test_xmlsupport.py: New. Tests for the xmlsupport module
1667    
1668            * test/test_save.py (SaveSessionTest): Derive from ValidationTest
1669            so that we can validate the
1670            (SaveSessionTest.testEmptySession)
1671            (SaveSessionTest.testSingleLayer)
1672            (SaveSessionTest.testSingleLayer)
1673            (SaveSessionTest.testLayerProjection)
1674            (SaveSessionTest.testRasterLayer)
1675            (SaveSessionTest.testClassifiedLayer): Validate the generated XML
1676    
1677            * test/runtests.py (main): Call print_additional_summary instead
1678            of print_garbage_information
1679    
1680            * test/support.py (resource_dir): New function to return the
1681            "Resource" subdirectory
1682            (print_additional_summary): New function to combine several
1683            summary functions
1684            (run_tests): Use print_additional_summary instead of calling
1685            print_garbage_information directly
1686    
1687    2003-06-19  Bernhard Herzog  <[email protected]>
1688    
1689            * Doc/thuban.dtd (classification): Correct the content model of
1690            the classification element.
1691            (projection): Add the "name" attribute
1692    
1693    2003-06-19  Frank Koormann   <[email protected]>
1694    
1695            MERGE from the greater-ms3 branch.
1696    
1697            * Thuban/UI/scalebar.py (ScaleBar.DrawScaleBar): Apply conversion to
1698            scale if projection is latlong to get better estimate.
1699    
1700            Fix problem of hidden properties dialog under windows after double
1701            click on layer tree:
1702            The tree control always gets an Expanded / Collapsed event after
1703            the ItemActivated  on double click, which raises the main window again.         We add a second ItemActivated event to the queue, which simply
1704            raises the already displayed window.
1705    
1706            * Thuban/UI/legend.py (LegendTree.__init__): Instance variable
1707            raiseProperties initialized to prevent endless loops
1708            (LegendTree._OnItemActivated): Depending on self.raiseProperties
1709            simply raise the properties or open the dialog and issue a second
1710            event.
1711    
1712    2003-06-18  Jonathan Coles   <[email protected]>
1713    
1714            * setup.py: Fix a few problems that occured under Windows.
1715    
1716    2003-06-18  Jonathan Coles   <[email protected]>
1717    
1718            When Thuban loaded the map was redrawn twice because the
1719            legend was being opened after the mainwindow was created
1720            and not during its creation. This meant the map was drawn
1721            initially and then had to be redrawn when the legend
1722            caused the display to change. Now the legend is opened
1723            in the mainwindow constructor which resolves this issue.
1724    
1725            Also, although we were checking for the existence of
1726            gdal and gdalwarp modules, the gdalwarp extension was
1727            still being compiled (which may fail if the system doesn't
1728            have gdal installed). the build_ext command to setup.py
1729            now accepts the flags --with-gdal and --without-gdal.
1730            If --without-gdal is specified setup.py will try to
1731            use the gdal parameters specified by gdal-config. Under
1732            windows, those parameters have to be set in setup.py
1733            as with proj4 an wxWindows.
1734    
1735            * setup.py: Use a list instead of seperate variables for
1736            extension parameters so we can create a generic function
1737            that runs an appropriate *-config script.
1738            (run_cs_script): Renamed from run_wx_script and modified
1739            to accept a second argument which is a list of lists to
1740            be filled in by the values returned from running the command.
1741            (thuban_build_ext): New. Extends the build_ext command and
1742            provides the options --with-gdal/--without-gdal which then
1743            optionally includes the gdalwarp extension.
1744    
1745            * Thuban/Model/resource.py: First check if we can import
1746            the gdalwarp Thuban extension before checking for gdal.
1747            Also added some comments.
1748            
1749            * Thuban/UI/legend.py (ScaleBarBitmap.__SetScale): Check if
1750            the map is None which may be the case if none has been loaded
1751            yet.
1752    
1753            * Thuban/UI/main.py (main): Remove call to ShowLegend.
1754    
1755            * Thuban/UI/mainwindow.py (MainWindow.__init__): Call ShowLegend().
1756    
1757            * Thuban/UI/renderer.py: Check for gdal support before importing
1758            gdalwarp.
1759            (MapRenderer.render_map): Only try to optimize if we have gdal
1760            support otherwise nothing will get drawn.
1761    
1762            * Thuban/UI/view.py (MapCanvas.FitMapToWindow): This may be called
1763            during startup before a map has been created. Check if map is None
1764            before using it and do nothing if it is.
1765    
1766    2003-06-17  Jonathan Coles   <[email protected]>
1767    
1768            Fix the problem with raster layers under Windows that caused
1769            Thuban to crash. The view should respond to layer projection
1770            changed events to update the display. Changes to a projection
1771            should not cause the map to be set to full extent.
1772            
1773            * Thuban/UI/view.py (MapCanvas.__init__): New instance variable
1774            current_map_proj to remember the current map projection so that
1775            when the projection changes we know what the previous projection
1776            was.
1777            (MapCanvas.SetMap): Unsubscribe and subscribe to
1778            LAYER_PROJECTION_CHANGED events.
1779            (MapCanvas.projection_changed): Split into two methods that respond
1780            to map and layer projection changes.
1781            (MapCanvas.map_projection_changed): New. Takes the current view and
1782            projects it using the new projection. This does not cause the
1783            map to be redrawn at full extent.
1784            (MapCanvas.layer_projection_changed): New. Cause a redraw which
1785            will draw each layer in its new projection.
1786            
1787            * extensions/thuban/bmpdataset.cpp (BMPDataset::Open): Call
1788            VSIFClose() not VSIFCloseL() to close the file. Fixes a crash
1789            under Windows.
1790            
1791            * extensions/thuban/gdalwarp.cpp (MFILENAME): Padding should be
1792            to twice sizeof(void*) because there are two digits for each
1793            hex byte.
1794    
1795    2003-06-16  Bernhard Herzog  <[email protected]>
1796    
1797            Update to the layer interface: Direct access to the table,
1798            shapetable, shapefile and filename attributes is now actively
1799            deprecated by issuing deprecation warnings for all places where
1800            this happens.
1801    
1802            * Thuban/Model/layer.py (Layer.__getattr__): New. Implement access
1803            to the instance variables table, shapetable, shapefile and
1804            filename via __getattr__ so that we can issue a deprecation
1805            warning.
1806            (Layer.SetShapeStore): Don't set the deprecated instance variables
1807            any more
1808            (Layer.SetShapeStore): Don't use deprecated layer instance
1809            variables
1810            (Layer.Destroy): No need to explicitly remove the instance
1811            variables any more
1812            (Layer.GetFieldType, Layer.Shape): Don't use deprecated layer
1813            instance variables
1814    
1815            * Thuban/UI/classgen.py (ClassGenDialog.__init__)
1816            (GenUniformPanel._OnRetrieve, GenUniquePanel._OnRetrieve)
1817            (GenQuantilesPanel.GetList, GenQuantilesPanel.OnRetrieve): Don't
1818            use deprecated layer instance variables
1819    
1820            * Thuban/UI/classifier.py (Classifier.__init__): Don't use
1821            deprecated layer instance variables
1822    
1823            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
1824            (IdentifyGridCtrl.selected_shape): Don't set the deprecated layer
1825            instance variables
1826    
1827            * Thuban/UI/tableview.py (LayerTableGrid.select_shapes): Don't use
1828            deprecated layer instance variables
1829    
1830            * Thuban/UI/mainwindow.py (MainWindow.LayerShowTable): Don't use
1831            deprecated layer instance variables
1832    
1833            * Thuban/Model/save.py (SessionSaver.write_layer): Don't use
1834            deprecated layer instance variables
1835    
1836            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer)
1837            (MapRenderer.polygon_render_param): Don't use deprecated layer instance
1838            variables
1839    
1840            * test/runtests.py (main): Turn Thuban's deprecation warnings into
1841            errors so that they're cought by the tests
1842    
1843            * test/test_load.py (TestSingleLayer.test): Don't use deprecated
1844            layer instance variables
1845    
1846    2003-06-16  Jonathan Coles   <[email protected]>
1847    
1848            Fix a problem under Windows whereby if the user double-clicks on a
1849            layer in the legend that tree item will expand or collapse as well
1850            as open the layer properties dialog. The state of the tree item
1851            should not be affected.
1852    
1853            * Thuban/UI/legend.py (LegendTree.__init__): Add instance variable
1854            preventExpandCollapse and subscribe to expanding and collapsing
1855            events.
1856            (LegendTree.OnItemExpandCollapse): New. Responds to expanding and
1857            collapsing events and will veto the event if it has been triggered
1858            by the user double clicking on a layer.
1859            (LegendTree._OnItemActivated): Set preventExpandCollapse to indicate
1860            that an expanding/collapsing event should be vetoed.
1861    
1862    2003-06-13  Bernhard Herzog  <[email protected]>
1863    
1864            * Thuban/UI/classifier.py (Classifier.OnClose)
1865            (Classifier.map_layers_removed)
1866            (Classifier.layer_shapestore_replaced): Unsubscribe the messages
1867            in OnClose and not in map_layers_removed or
1868            layer_shapestore_replaced to make sure it always happens when the
1869            dialog is closed
1870    
1871    2003-06-13  Jonathan Coles   <[email protected]>
1872    
1873            This puts back a fix for Windows where a panel is needed so that
1874            the background of the table view appears correctly.
1875    
1876            * Thuban/UI/tableview.py (TableFrame.__init__): Add a panel
1877            object that can be used by derived classes to place any
1878            controls (including the grid) onto.
1879            (QueryTableFrame.__init__): Use the panel as the parent window
1880            for all the controls. Reparent the grid so that the panel is
1881            the parent. Call UpdateStatusText() to correctly initialize
1882            the status bar.
1883    
1884    2003-06-13  Jonathan Coles   <[email protected]>
1885    
1886            * Thuban/UI/dialogs.py (ThubanFrame): New: a class that inherits
1887            from wxFrame (as opposed to wxDialog like the other classes)
1888            but otherwise behaves like the other classes. This is needed
1889            for the TableView which isn't really a dialog and needs to
1890            have a status bar and control buttons.
1891    
1892            * Thuban/UI/tableview.py (TableGrid.__init__): Create an
1893            instance variable to keep track of how many rows are selected.
1894            Subscribe once to the the events we are interested in.
1895            (ThubanGrid.OnRangeSelect): Only handle event if event handling
1896            hasn't been turned off.
1897            (ThubanGrid.OnSelectCell): Only handle event if event handling
1898            hasn't been turned off.
1899            (ThubanGrid.ToggleEventListeners): Rather than subscribe None
1900            as an event listener (which changes the event handler stack)
1901            simply set an instance variable to False. This is checked in
1902            the event handlers.
1903            (ThubanGrid.GetNumberSelected): Return the number of currently
1904            selected rows.
1905            (TableFrame): Inherit from ThubanFrame so we can have a
1906            status bar and control buttons.
1907            (QueryTableFrame.__init__): Create a status bar. Fixes RTbug #1942.
1908            Explicitly set which items are selected in the operator choice and
1909            action choice so there is always a valid selection. Fixes RTbug #1941.
1910            Subscribe to grid cell selection events so we can update the
1911            status bar.
1912            (QueryTableFrame.UpdateStatusText): Update the status bar with
1913            how many rows are in the grid, how many columns, and how many
1914            rows are selected.
1915            (QueryTableFrame.OnGridSelectRange, QueryTableFrame.OnGridSelectCell):
1916            Call UpdateStatusText when cells are (de)selected.
1917            (QueryTableFrame.OnQuery): Use the string value in the value
1918            combo if either the selected item index is 0 or if the string
1919            cannot be found in the predefined list (this happens if the
1920            user changes the text). Fixes RTbug #1940.
1921            Only turn off the grid event listeners if there a query comes
1922            back with a none empty list of ids. in the case that the list
1923            is empty this causes a grid.ClearSelection() call to actually
1924            clear the grid selection which causes the selected items in
1925            the map to be deselected. Fixes RTbug #1939.
1926    
1927            * test/test_save.py (XMLWriterTest.Encode): Check return values.
1928            Fixes RTbug #1851.

1931    
1932            * Thuban/UI/identifyview.py (IdentifyView.__init__): Call
1933            self.selected_shape with the current selection to make sure the
1934            contents of the dialog are up to date when it's shown for the
1935            first time.
1936            The dialog used to work without this by luck. The recent fix to
1937            the connector module 'broke' a 'feature' the identify view was
1938            relying on, i.e that subscribing to a message in response to
1939            receiving a message of that type would mean that the new
1940            subscriber would also be called for the same message.
1941

1950            user directory if it doesn't exist on a posix system.
1951            Fixes RTbug #1815.
1952    
1953            * Thuban/Model/resource.py (get_user_proj_files): Moved the
1954            called to get_application_dir here, so that the directory
1955            will only be called if this method is invoked.
1956    
1957            * Thuban/UI/projdialog.py (ProjFrame.__DoOnProjAvail): Clear
1958            the projfilepath if no projection is selected.

1966            projfilepath label to just the basename of the projection file
1967            rather than include the entire path.

1975            tested if the variable was an instance of Color.
1976    
1977            * Thuban/Model/color.py (Color): Remove commented code that isn't
1978            used.
1979            (Transparent): Renamed from NoColor. Doesn't inherit from Color.
1980            Fixes RTbug #1835.
1981            (Transparent.__eq__, Transparent.__ne, Transparent.__repr): New.
1982            Needed now that the class doesn't inherit from Color.
1983    
1984    2003-06-12  Jonathan Coles   <[email protected]>

1999    2003-06-12  Jonathan Coles   <[email protected]>
2000    
2001            This is largely a collection of bug fixes. We also handle the
2002            case where gdal is not on the system. The XMLReader and XMLWriter
2003            classes were moved into there own files to resolve some circular
2004            import references and because they shouldn't really be in the
2005            file that is dediciated to reading/writing session files since

2112    
2113            * Thuban/Lib/connector.py (Connector.Issue): Iterate over a copy

2131            * Thuban/UI/classifier.py (Classifier.__init__): Add the map as
2132            parameter so we can subscribe to some of its messages
2133            (Classifier.__init__): Subscribe to the map's MAP_LAYERS_REMOVED
2134            and the layer's LAYER_SHAPESTORE_REPLACED
2135            (Classifier.unsubscribe_messages): New. Unsubscribe from message

2137            (Classifier.map_layers_removed)
2138            (Classifier.layer_shapestore_replaced): receivers for the messages

2171    
2172            * Thuban/UI/projdialog.py (ProjFrame.__init__): Fill the projchoice
2173            once on initialisation (Former implementation resulted in multiple

2176            if set, select the projection found under the specified name. This
2177            overwrites any other selection estimate.
2178            Removed projchoice filling from this method.
2179            (ProjFrame._OnSave, ProjFrame._OnAddToList):

2198    
2199            Do not cache the values returned by the tree widget's
2200            GetFirstChild and GetNextChild methods because it led to lots of
2201            segfaults. The new way requires more brute force but is more
2202            reliable.
2203    
2204            * Thuban/UI/legend.py (LegendTree.__init__): Remove instance
2205            variable layer2id
2206            (LegendTree.find_layer): New method to do with brute force what
2207            layer2id tried to accomplish
2208            (LegendTree._OnMsgLayerChanged)
2209            (LegendTree._OnMsgLayerTitleChanged, LegendTree.__ShowHideLayer):
2210            Use find_layer instead of layer2id
2211            (LegendTree.__RemoveLayer, LegendTree.__AddLayer): No need to
2212            update layer2id anymore
2213            (LegendTree._OnMsgMapLayersRemoved)
2214            (LegendTree._OnMsgMapLayersAdded): Get by without layer2id.

2234            whether the modified flag is set properly
2235    
2236            * Thuban/Model/base.py (TitledObject.SetTitle): Call changed
2237            instead of issue so that the modified flags get updated.
2238    
2239            * test/test_base.py (SomeTitledObject): Derive from Modifiable
2240            instead of Publisher to reflect reality better and to accomodate
2241            the fact that SetTitle now calls changed instead of issue
2242    
2243    2003-06-02  Bernhard Herzog  <[email protected]>
2244    
2245            * Thuban/UI/classgen.py (GenQuantilesPanel.GetList): Resource

2249    
2250            * Thuban/UI/legend.py (LegendTree._OnMsgMapLayersRemoved): It's
2251            possible that a layer is removed that is not currently selected in

2253    
2254    2003-05-30  Bernhard Herzog  <[email protected]>
2255    
2256            * Thuban/Model/layer.py (Layer.Destroy): Set all instance
2257            variables to None that have direct or indirect references to
2258            shapefiles or dbf files to make sure that they do go away and the
2259            files are closed.

2267    
2268            * Thuban/UI/legend.py (LegendTree.__init__): New instance variable
2269            changing_selection to indicate whether the LegendTree code itself
2270            is currently changing the selection
2271            (LegendTree.normalize_selection): New method to normalize the
2272            selection by selecting the layer item even if the user clicked on
2273            the classification.
2274            (LegendTree._OnSelChanged): normalize the selection. This works
2275            around a bug in wx which doesn't keep track of the selection

2296            of the ClassGenerator class. Put try/finally blocks around

2334            to be compiled as a standalone app. Now the code can only be
2335            called from Python which simplifies the parameter passing.
2336            (ProjectRasterFile): Handle Python arguments. Remove code that
2337            checks for a destination dataset. Add more clean up code.
2338

2658            New. Test for AddShapeStore
2659    
2660    2003-05-23  Jan-Oliver Wagner <[email protected]>
2661    
2662            Introducing QueryTableFrame and a very coarse ShowTable implementation.
2663    
2664            * Thuban/UI/tableview.py (LayerTableFrame, QueryTableFrame): Split the
2665            class LayerTableFrame into two classes, LayerTableFrame and QueryTableFrame.
2666            The latter implements the selection GUI without dependency on a layer.
2667            LayerTableFrame now is derived from QueryTableFrame and connects
2668            to a layer.
2669    
2670            * Thuban/UI/mainwindow.py (MainWindow.TableShow): A very coarse
2671            implementation that still needs work.
2672    
2673            * Thuban/Model/layer.py (Layer.TreeInfo): Added filename.
2674    
2675    2003-05-22  Frank Koormann  <[email protected]>
2676    
2677            * Thuban/Model/transientdb.py (TransientJoinedTable.__init__):
2678            Added "outer_join = False" as optional parameter.
2679            (TransientJoinedTable.create): If outer join is true, perform a
2680            "LEFT OUTER JOIN" instead of "JOIN", which preserves all records of
2681            the left table. Records not matching are filled with 0 / None.
2682    
2683            * Thuban/UI/join.py (JoinDialog.__init__): Checkbox for outer join.
2684            (JoinDialog.OnJoin): Consider outer join check box.
2685    
2686    2003-05-22  Bernhard Herzog  <[email protected]>
2687    
2688            * Thuban/UI/join.py (JoinDialog.OnJoin): Use exc_info in a
2689            somewhat safer way. Storing the traceback in a local variable can
2690            lead to memory leaks
2691    
2692    2003-05-22  Bernhard Herzog  <[email protected]>
2693    
2694            * Thuban/UI/join.py (JoinDialog.OnJoin): Make sure to really call
2695            the wxMessageDialog's Destroy() method.
2696    
2697    2003-05-22  Frank Koormann  <[email protected]>
2698    
2699            * Thuban/UI/join.py (JoinDialog.__init__): Make use of
2700            TransientTable.Title()
2701    
2702    2003-05-22  Frank Koormann  <[email protected]>
2703    
2704            Join Dialog, initial version.
2705    
2706            * Thuban/UI/mainwindow.py (MainWindow.TableJoin): Removed print.
2707    
2708            * Thuban/UI/join.py (JoinDialog): Functional implementation of
2709            former framework. Renamed Table1/Table2 to LeftTable/RightTable
2710            in all occurences.
2711    
2712            * Thuban/Model/transientdb.py (TransientJoinedTable.__doc__):
2713            Typo fixed.
2714    
2715    2003-05-22  Bernhard Herzog  <[email protected]>
2716    
2717            Give the tables titles so that the GUI can display more meaningful
2718            names. For now the titles are fixed but depend on e.g. filenames
2719            or the titles of the joined tables.
2720    
2721            * Thuban/Model/transientdb.py (TransientTable.Title)
2722            (TransientJoinedTable.Title, AutoTransientTable.Title): New.
2723    
2724            * Thuban/Model/table.py (DBFTable.Title, MemoryTable.Title): New.
2725    
2726            * test/test_transientdb.py
2727            (TestTransientTable.test_auto_transient_table_title): New. Test
2728            for the Title method
2729            (TestTransientTable.test_transient_joined_table)
2730            (TestTransientTable.test_transient_table): Add test for the Title
2731            methods
2732    
2733            * test/test_memory_table.py (TestMemoryTable.test_title): New.
2734            Test for the Title method
2735    
2736            * test/test_dbf_table.py (TestDBFTable.test_title): New. Test for
2737            the Title method
2738    
2739    2003-05-22  Bernhard Herzog  <[email protected]>
2740    
2741            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
2742            Provide a better way to destroy the layers
2743            (TestLayer.test_base_layer, TestLayer.test_arc_layer)

2750            * Thuban/Model/layer.py (Layer.SetShapeStore): Only set the
2751            filename if the shape store actually has one.
2752    
2753    2003-05-22  Bernhard Herzog  <[email protected]>
2754    
2755            * Thuban/Model/table.py (DBFTable.FileName): New. Accessor method
2756            for the filename
2757    
2758            * test/test_dbf_table.py (TestDBFTable.test_filename): New. Test
2759            for the FileName method
2760            (TestDBFTableWriting.test_write): Fix spelling of filename
2761    
2762    2003-05-22  Thomas Koester  <[email protected]>
2763    
2764            * Thuban/Model/range.py, test/test_range.py: Brought over new Range
2765            from SciParam that now really is immutable.
2766    
2767    2003-05-22  Frank Koormann  <[email protected]>
2768    
2769            Layer Top/Bottom placement added to legend.
2770    
2771            * Thuban/UI/legend.py
2772            (LegendPanel._OnMoveTop(), LayerPanel._OnMoveBottom): New, methods
2773            bound to tool events.
2774            (LegendTree.MoveCurrentItemTop(), LegendTree.MoveCurrentItemBottom):
2775            New, methods binding the event methods with the map methods.
2776    
2777            * Thuban/Model/map.py (Map.TopLayer(), Map.BottomLayer()): New, place
2778            layer at top/bottom of layer stack.
2779    
2780            * Resources/Bitmaps/top_layer.xpm: New button icon.
2781    
2782            * Resources/Bitmaps/bottom_layer.xpm: New button icon.
2783    
2784    2003-05-22  Bernhard Herzog  <[email protected]>
2785    
2786            * Thuban/Model/session.py (Session.RemoveTable): New method to
2787            remove tables
2788    
2789            * test/test_session.py (TestSessionSimple.test_remove_table): New.
2790            Test for RemoveTable
2791    
2792    2003-05-22  Thomas Koester  <[email protected]>
2793    
2794            * Thuban/Model/classgen.py: Added short module doc string and CVS id.
2795            (ClassGenerator.GenUniformDistribution): Use new Range __init__, too.
2796    
2797    2003-05-22  Bernhard Herzog  <[email protected]>
2798    
2799            Implement a way to discover dependencies between tables and
2800            shapestores.
2801    
2802            * Thuban/Model/transientdb.py (TransientTableBase.Dependencies)
2803            (TransientJoinedTable.Dependencies)
2804            (AutoTransientTable.SimpleQuery): New. Implement the dependencies
2805            interface
2806            (TransientJoinedTable.__init__): Keep tack of the original table
2807            objects in addition to the corresponding transient tables.
2808    
2809            * Thuban/Model/table.py (DBFTable.Dependencies)
2810            (MemoryTable.Dependencies): New. Implement the dependencies
2811            interface
2812    
2813            * Thuban/Model/data.py (ShapeTable): New. Helper class for
2814            ShapefileStore
2815            (ShapefileStore.__init__): Use ShapeTable instead of
2816            AutoTransientTable
2817            (ShapefileStore.Table, ShapefileStore.Shapefile): Add doc-strings
2818            (ShapefileStore.FileName, ShapefileStore.FileType): New. Accessor
2819            methods for filename and type
2820            (ShapefileStore.Dependencies): New. Implement the dependencies
2821            interface
2822            (DerivedShapeStore): New class to replace SimpleStore. The main
2823            difference to SimpleStore is that it depends not on a shapefile
2824            but another shapestore which expresses the dependencies a bit
2825            better
2826            (SimpleStore.__init__): Add deprecation warning.
2827    
2828            * test/test_dbf_table.py (TestDBFTable.test_dependencies): New.

2833    
2834            * test/test_transientdb.py
2835            (TestTransientTable.test_auto_transient_table_dependencies): New.
2836            Test for the Dependencies method.
2837            (TestTransientTable.test_transient_joined_table): Add test for the
2838            Dependencies method.
2839    
2840            * test/test_session.py (TestSessionSimple.setUp)
2841            (TestSessionSimple.tearDown): New. Implement a better way to
2842            destroy the sessions.
2843            (TestSessionSimple.test_initial_state)
2844            (TestSessionSimple.test_add_table): Bind session to self.session
2845            so that it's destroyed by tearDown
2846            (TestSessionSimple.test_open_shapefile): New. Test for
2847            OpenShapefile and the object it returns
2848    
2849    2003-05-22  Bernhard Herzog  <[email protected]>
2850    
2851            * Thuban/Model/session.py (Session.AddTable): New method to
2852            register tables with the session.
2853            (Session.Tables): Return the tables registered with AddTable too.
2854    
2855            * test/test_session.py (TestSessionSimple.test_add_table): New.
2856            Test case for the AddTable method
2857    
2858    2003-05-22  Frank Koormann  <[email protected]>
2859    
2860            UI polishing updates: Place main buttons (OK, Cancel, etc) in the
2861            lower right corner, center labels for selections, initialize controls
2862            in reasonable order for keyboard navigation.
2863    
2864            * Thuban/UI/projdialog.py (ProjFrame.__init__, ProjFrame.__doLayout)
2865            (ProjFrame.__DoOnProjAvail): Determine position of current projection
2866            using the wxListBox.FindString() method. Still a problem (#1886)
2867    
2868            * Thuban/UI/classifier.py
2869            (Classifier.__init__, SelectPropertiesDialog.__init__)
2870    
2871            * Thuban/UI/classgen.py (ClassGenDialog.__init__,
2872            (ClassGenDialog.__DoOnGenTypeSelect): Moved initialization of the
2873            different classification types from here to __init__.
2874            (GenUniquePanel.__init__): Set the column width of the first field
2875            in the Field ListCtrl to the full width.
2876    
2877            * Thuban/UI/tableview.py (LayerTableFrame.__init__): Rename 'Save As'
2878            Button to 'Export'. Center Buttons in Selection Box, set Focus to
2879            Grid.
2880            (LayerTableFrame.OnKeyDown()): New, bound to the grid with EVT_KEY_DOWN,
2881            changes focus to the Selection when pressing "Alt-S".
2882    
2883            * Thuban/UI/legend.py (LegendTree.__SetVisibilityStyle): Only gray out
2884            the text if not visible. The italic font sometimes exceeds the
2885            rendering area.
2886    
2887    2003-05-21  Jonathan Coles   <[email protected]>
2888    
2889            * Thuban/UI/dock.py (DockFrame): Rename references to _OnClose
2890            to OnClose so that Thuban closes correctly.
2891    
2892            * Thuban/UI/mainwindow.py (MainWindow.OnClose): Call
2893            DockFrame.OnClose, not DockFrame._OnClose.
2894    
2895    2003-05-21  Jonathan Coles   <[email protected]>
2896    
2897            * Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove
2898            references to 'inf' and use new Range __init__ to pass floats
2899            directly rather than converting them to strings first.
2900            Fixes RTBug #1876.
2901    
2902            * Thuban/Model/classification.py (ClassGroupRange.SetRange):
2903            Use new Range ___init__ to pass floats.
2904    
2905            * Thuban/Model/layer.py (RasterLayer.__init__): Test if the
2906            filename is a valid image file. Throw IOError otherwise.
2907    
2908            * Thuban/Model/range.py: Brought over new Range from SciParam that
2909            is immutable and has an __init__ which can accept floats.
2910    
2911            * Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile
2912            into try block. AddLayer doesn't throw any exceptions anymore.
2913            (MainWindow.AddRasterLayer): Move constructor of RasterLayer into
2914            try block.
2915    
2916            * Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as
2917            the first item in choices. Fixes RTBug #1882.
2918    
2919            * Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale
2920            has gone to 0 which is a serious problem. abort.
2921            (MapRenderer.draw_raster_layer): Catch IOError seperately and
2922            print the error from GDAL.
2923    
2924            * Thuban/UI/tableview.py (TableGrid.__init__): Call
2925            ToggleEventListeners to turn on listening.
2926            (TableGrid.ToggleEventListeners): New. Turns event listening on
2927            and off so as to prevent excessive messages.
2928            (LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners
2929            to suppress excessive messages when selecting many rows.
2930            Fixes RTBug #1880.
2931    
2932            * Thuban/UI/view.py: Added checks against if scale == 0. This
2933            is a serious problem that can occur when an image without
2934            geo data is loading and causes the map projection bounds to
2935            go to infinity. Right now, the solution is to simply try
2936            to recover.
2937    
2938            * extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure
2939            to set the MFILEReceiver attributes even if the data is NULL.
2940    
2941            * extensions/thuban/gdalwarp.cpp: Improved the error handling
2942            and passed GDAL messages back up to the Python layer. Also
2943            tried to fix some memory leaks that were present in the original
2944            utility but didn't matter because the program aborted.
2945    
2946            * test/test_range.py: Copied over tests from SciParam. Removed
2947            tests against importing. Fixes RTBug #1867.
2948    
2949    2003-05-21  Bernhard Herzog  <[email protected]>
2950    
2951            * test/test_load.py: Remove unused imports and restructure the
2952            test code
2953            (LoadSessionTest): Split into one class for each test and turn
2954            LoadSessionTest itself into the base class for all such session
2955            tests.
2956            (ClassificationTest): New base class for load tests that test
2957            classifications
2958            (TestSingleLayer, TestLayerVisibility, TestClassification)
2959            (TestLabels, TestLayerProjection, TestRasterLayer): New classes
2960            for the individual tests
2961    
2962            * test/support.py (FileLoadTestCase.filename): New base class for
2963            file loading tests
2964    
2965    2003-05-21  Jan-Oliver Wagner <[email protected]>
2966    
2967            * Resources/Projections/defaults.proj: Renamed 'Universal Transverse
2968            Mercator' to 'UTM Zone 32' as a more convenient example.
2969            Added 'Gauss Krueger Zone 6'.
2970    
2971            * Data/iceland_sample_raster.thuban: political polygon now
2972            filled transparent to have the raster image visible at once.
2973    
2974    2003-05-21  Frank Koormann  <[email protected]>
2975    
2976            * Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to
2977            OnClose() to keep in sync with extensions. Internally Thuban
2978            still uses "underscored" names.
2979    
2980    2003-05-20  Jonathan Coles   <[email protected]>
2981    
2982            This puts back Raster layer support. These layers support projections
2983            through the GDAL library. Currently, the CVS version is being used.
2984            There are no Debian packages available although this may change soon.
2985            A GDAL driver was extended to support writing to memory rather to
2986            files.
2987    
2988            There is still some work that needs to be done, such as some error
2989            handling when loading invalid images or when there is a problem
2990            projecting the image. This putback simply checks in the majority
2991            of the work.
2992    
2993            * setup.py: Add gdalwarp library extension.
2994    
2995            * Thuban/Model/layer.py (BaseLayer.HasClassification): New.
2996            Defaults to False, but can be overridden by subclasses if they
2997            support classification.
2998            (RasterLayer): New. Defines a new layer that represents an
2999            image.
3000    
3001            * Thuban/Model/load.py (SessionLoader.__init__): Add rasterlayer
3002            tag handler.
3003            (SessionLoader.start_layer): Encode the filename.
3004            (SessionLoader.start_rasterlayer, SessionLoader.end_rasterlayer):
3005            New. Supports reading a rasterlayer tag.
3006    
3007            * Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment.
3008    
3009            * Thuban/Model/save.py (XMLWriter.encode): Don't assume that we
3010            get a string in Latin1. If we get such as string convert it to
3011            unicode first, otherwise leave if alone before encoding.
3012            (SessionSaver.write_layer): Add support for writing both Layers
3013            and RasterLayers.
3014    
3015            * Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery):
3016            The right argument may not be a string, it could also be a Column.
3017    
3018            * Thuban/UI/application.py (ThubanApplication.CreateMainWindow):
3019            Make initial window size 600x400. Fixes RTBug #1872.
3020    
3021            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange how
3022            the dialog is constructed so that we can support layers that
3023            do not have classifications.
3024            (Classifier._OnTry): Only build a classification if the layer
3025            supports one.
3026    
3027            * Thuban/UI/legend.py: Change all checks that a layer is an
3028            instance of Layer into checks against BaseLayer.
3029            (LegendTree.__FillTreeLayer): Only add children to a branch if
3030            the layer supports classification.
3031    
3032            * Thuban/UI/mainwindow.py (MainWindow.NewSession,
3033            MainWindow.OpenSession): Don't proceed with an action if the
3034            user chooses Cancel when they are asked to save changes.
3035            (MainWindow.AddRasterLayer): New. Open a dialog to allow the
3036            user to select an image file. Create a new RasterLayer and add

3270            * Thuban/UI/tableview.py (TableGrid.OnRangeSelect): Fix some issues
3271            with correctly selecting the rows and issuing the right events.
3272            Be sure to call Skip() to allow the grid to do some of its own
3273            handling which allows the rows to actually be selected.
3274            (LayerTableGrid.select_shapes): Rename from select_shape. Supports
3275            selecting multiple shapes.
3276            (LayerTableFrame): Support for building Queries.

3423            * Thuban/Model/table.py (OldTableInterfaceMixin): All methods
3424            issue deprecation warnings when they're. The warnings refer to the
3425            caller of the method.
3426            (OldTableInterfaceMixin.__deprecation_warning): New. Helper method
3427            for the deprecation warnings
3428    
3429            * test/test_table.py: Ignore the deprecation warnings for the old
3430            table in the tests in this module. The purpose of the tests is to
3431            test the old interface, after all.

3456    
3457            * Thuban/Model/transientdb.py (TransientTableBase.HasColumn)
3458            (AutoTransientTable.HasColumn): Implement the new table interface
3459            method
3460            (AutoTransientTable.ReadRowAsDict, AutoTransientTable.ValueRange)
3461            (AutoTransientTable.UniqueValues): Adapt to new table interface
3462

3480    
3481            Addresses the "Selection Extent" wish of RTbug #1787.
3482    
3483            * Resources/Bitmaps/fulllayerextent.xpm,
3484            Resources/Bitmaps/fullselextent.xpm: Bitmaps for layer and selection
3485            extent. These are just place holders for the real bitmaps.
3486    
3487            * Thuban/Model/layer.py (Shape): Since a Shape is immutable only
3488            calculate the bounding box once (the first time compute_bbox() is
3489            called).
3490            (Layer.ShapesBoundingBox): New. Given a list of shape ids, return
3491            the bounding box for the shapes in lat/long coordinates.
3492    
3493            * Thuban/UI/mainwindow.py: Added new "Full selection extent" menu
3494            option.

3503            true if there are any selected shapes.
3504    
3505            * Thuban/UI/view.py (MapCanvas): Added delegated method
3506            HasSelectedShapes.

3508            shapes on the canvas using the map projection (if any).
3509    
3510            * test/test_layer.py (TestLayer.test_arc_layer): Add some tests
3511            for Layer.ShapesBoundingBox().

3519            Addresses the "Full Layer Extent" wish of RTbug #1787.
3520    
3521            * Resources/Projections/defaults.proj: Added UK National Grid.
3522    
3523            * Thuban/UI/mainwindow.py: Added new "Full layer extent" menu option.

3530    2003-05-05  Bernhard Herzog  <[email protected]>
3531    
3532            Convert the table implementations to a new table interface. All
3533            tables use a common mixin class to provide backwards compatibility
3534            until all table users have been updated.
3535    
3536            * Thuban/Model/table.py (OldTableInterfaceMixin): Mixin class to
3537            provide backwards compatibility for table classes implementing the
3538            new interface
3539            (DBFTable, MemoryTable): Implement the new table interface. Use
3540            OldTableInterfaceMixin as base for compatibility
3541            (DBFColumn, MemoryColumn): New. Column description for DBFTable
3542            and MemoryTable resp.
3543    
3544            * test/test_dbf_table.py: New. Test cases for the DBFTable with
3545            the new table interface.
3546    
3547            * test/test_memory_table.py: New. Test cases for the MemoryTable
3548            with the new table interface.
3549    
3550            * test/test_table.py: Document the all tests in this file as only
3551            for backwards compatibility. The equivalent tests for the new
3552            interface are in test_memory_table.py and test_dbf_table.py
3553            (MemoryTableTest.test_read): field_info should be returning tuples
3554            with four items
3555            (MemoryTableTest.test_write): Make doc-string a more precise.
3556    
3557            * Thuban/Model/transientdb.py (TransientTableBase): Convert to new
3558            table interface. Derive from from OldTableInterfaceMixin for
3559            compatibility.
3560            (TransientTableBase.create): New intance variable column_map to
3561            map from names and indices to column objects
3562            (TransientTable.create): Use the new table interface of the input
3563            table
3564            (AutoTransientTable): Convert to new table interface. Derive from
3565            from OldTableInterfaceMixin for compatibility.
3566            (AutoTransientTable.write_record): Removed. It's not implemented
3567            yet and we still have to decide how to handle writing with the new
3568            table and data framework.
3569    
3570            * test/test_transientdb.py
3571            (TestTransientTable.run_iceland_political_tests)
3572            (TestTransientTable.test_transient_joined_table): Use the new
3573            table interface

3575    2003-05-05  Jonathan Coles   <[email protected]>
3576    
3577            This is namely a collection of UI updates to improve user interactivity.
3578            Tabbing between controls now exists and you can use ESC to close dialog
3579            boxes; ENTER will active the default button.
3580    
3581            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Rearrange the
3582            order that the controls are created so that tabbing works correctly.
3583            (ClassGenDialog.OnOK): Renamed from _OnGenerate() so that the
3584            wxDialog can handle the default button correctly.
3585            (ClassGenDialog.OnCancel): Renamed from _OnCloseBtn() for the
3586            same reasons as for OnOK.
3587            (GenUniformPanel._OnRetrieve): Call wxBeginBusyCursor/wxEndBusyCursor
3588            when we ask the table for the maximum/minimum values of a field
3589            which could take a very long time.
3590    
3591            * Thuban/UI/classifier.py (Classifier.__init__): Rearrange the
3592            order that the controls are created so that tabbing works correctly.
3593            (SelectPropertiesDialog.__init__): Rearrange the order that the
3594            controls are created so that tabbing works correctly.
3595    
3596            * Thuban/UI/dialogs.py: Copied NonModalDialog box and changed it
3597            to derive from a wxDialog but behave like the original implementation
3598            which was derived from a wxFrame. wxDialog provides useful key
3599            handling functionality like ESC calling OnCancel and ENTER calling
3600            OnOK which is lost with wxFrame.
3601    
3602            * Thuban/UI/mainwindow.py: Add "..." to menu items that will open
3603            new dialogs.
3604    
3605            * Thuban/UI/projdialog.py (ProjFrame.__init__): Rearrange the
3606            order that the controls are created so that tabbing works correctly.
3607            (ProjFrame.OnApply): Renamed from _OnTry() to use wxDialog behaviour.
3608            (ProjFrame.OnOK): Renamed from _OnOK() to use wxDialog behaviour.
3609            (ProjFrame.OnCancel): Renamed from _OnClose() to use wxDialog behaviour.
3610            (ProjPanel.__init__): Add "Airy" to the list of ellipsoids so we
3611            can provide the "UK National Grid" as a default projection.
3612            (UTMPanel.__init__): Rearrange the order that the controls are
3613            created so that tabbing works correctly.
3614    
3615    2003-05-05  Bernhard Herzog  <[email protected]>
3616    
3617            * extensions/thuban/wxproj.cpp: Fix some of the comments.
3618            (project_point): If a map projection but no layer projection is
3619            given, convert degrees to radians before applying the map
3620            projection.
3621    
3622            * Thuban/UI/tableview.py (TableGrid.disallow_messages)
3623            (TableGrid.allow_messages): New methods to make it possible to
3624            inhibit message sending.
3625            (TableGrid.issue): Only send the message if not inhibited.
3626            (LayerTableGrid.select_shape): Use the new methods to make sure
3627            that no ROW_SELECTED message is sent while we're updating the
3628            selected rows to match the selected shapes.

3631    
3632            Implementation of MemoryTable.
3633    
3634            * Thuban/Model/table.py (MemoryTable): New. Quite simple table
3635            implementation that operates on a list of tuples. All of the data
3636            are kept in the memory.
3637    
3638            * test/test_table.py (MemoryTableTest): New.
3639    
3640            * test/test_transientdb.py (SimpleTable): Removed.
3641            (TestTransientTable.test_transient_joined_table,
3642            (TestTransientTable.test_transient_table_read_twice): Replaced
3643            SimpleTable by MemoryTable.
3644    
3645    2003-04-30  Jonathan Coles   <[email protected]>
3646    
3647            * Data/iceland_sample.thuban: Now contains correct projections
3648            for each of the layers.
3649    
3650            * Resources/Projections/defaults.proj: Geographic projection
3651            contains unit conversion parameter.
3652    
3653    2003-04-30  Jonathan Coles   <[email protected]>
3654    
3655            The most important part of this putback is the projection changes.
3656            It should now be possible to specify the projection that a layer
3657            is in and then specify a different projection for the map. The
3658            projection dialog has an extra parameter for a geographic projection
3659            which lets the user select if the input is in degrees or radians.
3660    
3661            * Thuban/Model/layer.py (Layer.ShapesInRegion): Fix docstring
3662            to say that the parameter is a tuple of unprojected
3663            points (which is what the callers to this method were assuming).
3664            Also, since the points are unprojected we need to projected them.
3665    
3666            * Thuban/UI/legend.py (LegendTree.MoveCurrentItemUp,
3667            LegendTree.MoveCurrentItemDown): If the layer or any of the layer's
3668            groups are selected, move the layer up/down. Fixes RTbug #1833.
3669    
3670            * Thuban/UI/mainwindow.py: Move menu item map_rename up.
3671    
3672            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Add missing
3673            parameter in call to SetClientData.
3674            (GeoPanel): Add support for selecting the units that the
3675            source data is in (Radians or Degrees).
3676    
3677            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Optimize
3678            the rendering loop by reducing the number of if's, removing the
3679            unnecessary try/except block, and checking if the old group
3680            is the same as the new one (which happens a lot if there is
3681            no classification, or lots of shapes are in the same group).
3682    
3683            * Thuban/UI/view.py (MapCanvas.OnPaint): Add a try/except block
3684            around the redraw routine to try to catch problems that the user
3685            may create by selecting invalid projections for the data set and
3686            map. Clears the display if there are any problems and prints the
3687            error.
3688            (MapCanvas.do_redraw): Use DC.Clear() instead of drawing a filled
3689            rectangle.
3690    
3691            * extensions/thuban/wxproj.cpp (project_point): First invert the
3692            supplied point (which should be in projected coordinates) using
3693            the layer's projection and then project the point using the
3694            map's projection.
3695            (project_points): Use project_point() to project each point.
3696    
3697    2003-04-30  Jan-Oliver Wagner <[email protected]>
3698    
3699            * Thuban/Model/layer.py (Layer.SetShapeStore): Fixed a bug:
3700            don't set the Classification to None if the classfication field
3701            is None (ie only a DEFAULT).
3702    
3703    2003-04-30  Bernhard Herzog  <[email protected]>
3704    
3705            * Thuban/UI/view.py: Fix some typos.
3706    
3707            * Thuban/UI/mainwindow.py (MainWindow.identify_view_on_demand): Do
3708            not pop up the dialog if the selection becomes empty (this could
3709            happen if e.g. a new selection is opened while the identify tool
3710            is active and dialog had been closed)
3711    
3712    2003-04-30  Bernhard Herzog  <[email protected]>
3713    
3714            * Thuban/Model/transientdb.py (TransientTableBase.__init__): New
3715            instance variable read_record_last_result
3716            (TransientTableBase.read_record): Make sure reading the same
3717            record twice works. The implementation uses the new instance
3718            variable read_record_last_result
3719    
3720            * test/test_transientdb.py
3721            (TestTransientTable.test_transient_table_read_twice): New test
3722            case for the above bug-fix.
3723    
3724    2003-04-29  Jonathan Coles   <[email protected]>
3725    
3726            * Thuban/common.py: Removed. No longer needed Str2Num. RTbug #1832.
3727    
3728            * Thuban/UI/classgen.py: Remove all uses of Str2Num.
3729    
3730            * Thuban/UI/classifier.py: Remove all uses of Str2Num.
3731            (ClassTable.SetValueAsCustom): Rename keyword argument in
3732            ClassGroup* constructors to match argument name.
3733    
3734    2003-04-29  Bernhard Herzog  <[email protected]>
3735    
3736            * Thuban/Model/session.py (Session.Destroy): Explicitly close the
3737            transient DB if it exists to make sure it doesn't leave a journal
3738            file in the temp directory.
3739    
3740            * Thuban/Model/transientdb.py (TransientDatabase.close): Set
3741            self.conn to None after closing the connection to make sure it's
3742            not closed twice
3743    
3744    2003-04-29  Jonathan Coles   <[email protected]>
3745    
3746            Add a visible parameter in the layer XML tag. The default value is
3747            "true". If anything other than "false" is specified we also assume
3748            "true". Addresses RTbug #1025.
3749    
3750            * Doc/thuban.dtd: Add visible parameter to a layer.
3751    
3752            * Thuban/Model/layer.py (BaseLayer.__init__): Change default value
3753            of visible from 1 to True.
3754            (Layer.__init__): Change default value of visible from 1 to True.

3765            is loaded correctly.
3766    
3767            * test/test_save.py (SaveSessionTest.testSingleLayer): Add test
3768            for saving an invisible layer.
3769    
3770    2003-04-29  Jonathan Coles   <[email protected]>
3771    
3772            * Thuban/UI/mainwindow.py (MainWindow.SetMap): Look up the
3773            legend dialog box and tell it to change its map to the one
3774            supplied to SetMap(). Fixes RTbug #1770.
3775    
3776    2003-04-29  Bernhard Herzog  <[email protected]>
3777    
3778            Next step of table implementation. Introduce a transient database
3779            using SQLite that some of the data is copied to on demand. This
3780            allows us to do joins and other operations that require an index
3781            for good performance with reasonable efficiency. Thuban now needs
3782            SQLite 2.8.0 and pysqlite 0.4.1. Older versions may work but I
3783            haven't tested that.
3784            
3785            * Thuban/Model/transientdb.py: New. Transient database
3786            implementation.
3787    
3788            * test/test_transientdb.py: New. Tests for the transient DB
3789            classes.
3790    
3791            * Thuban/Model/session.py (AutoRemoveFile, AutoRemoveDir): New
3792            classes to help automatically remove temporary files and
3793            directories.
3794            (Session.__init__): New instance variables temp_dir for the
3795            temporary directory and transient_db for the SQLite database
3796            (Session.temp_directory): New. Create a temporary directory if not
3797            yet done and return its name. Use AutoRemoveDir to have it
3798            automatically deleted
3799            (Session.TransientDB): Instantiate the transient database if not
3800            done yet and return it.
3801    
3802            * Thuban/Model/data.py (ShapefileStore.__init__): Use an
3803            AutoTransientTable so that data is copied to the transient DB on
3804            demand.
3805            (SimpleStore): New class that simply combines a table and a
3806            shapefile
3807    
3808            * Thuban/Model/table.py (Table, DBFTable): Rename Table into
3809            DBFTable and update its doc-string to reflect the fact that this
3810            is only the table interface to a DBF file. Table is now an alias
3811            for DBFTable for temporary backwards compatibility.
3812    
3813            * Thuban/UI/application.py (ThubanApplication.OnExit): Make sure
3814            the last reference to the session goes away so that the temporary
3815            files are removed properly.
3816    
3817            * test/test_load.py (LoadSessionTest.tearDown): Remove the
3818            reference to the session to make sure the temporary files are
3819            removed.
3820    
3821    2003-04-29  Bernhard Herzog  <[email protected]>
3822    
3823            * Thuban/Model/load.py (XMLReader.__init__, XMLReader.read): Turn
3824            the __parser instance variable into a normal local variable in
3825            read. It's only used there and read will never be called more than
3826            once. Plus it introduces a reference cycle that keeps can keep the
3827            session object alive for a long time.
3828    
3829    2003-04-29  Jonathan Coles   <[email protected]>
3830    
3831            * Thuban/Model/proj.py (Projection): Removed Set*() methods to make
3832            Projection an immutable item. Fixes RTbug #1825.
3833            (Projection.__init__): Initialize instance variables here.
3834            (ProjFile.Replace): New. Replace the given projection object with
3835            the new projection object. This solves the problem of needing the
3836            mutator Projection.SetProjection() in the ProjFrame class and
3837            allows a projection to change parameters without changing its
3838            location in the file.
3839    
3840            * Thuban/UI/mainwindow.py (MainWindow.SaveSessionAs): Dialog should
3841            be of type wxSAVE and should verify overwriting a file.
3842    
3843            * Thuban/UI/projdialog.py (ProjFrame._OnSave): Use the new
3844            ProjFile.Replace() method instead of the mutator
3845            Projection.SetProjection(). Also requires that we reassign the
3846            client data to the new projection.
3847    
3848            * test/test_proj.py (TestProjection.test): Test GetName() and
3849            GetAllParameters()
3850            (TestProjFile.test): Remove tests for Set*() methods. Add tests
3851            for Replace().
3852    
3853    2003-04-25  Jonathan Coles   <[email protected]>
3854    
3855            * Thuban/Model/save.py (SessionSaver.write_projection): Make sure
3856            to save the name of the projection.
3857    
3858            * test/test_save.py (SaveSessionTest.testLayerProjection): New
3859            test to verify layer projections are saved correctly.
3860    
3861    2003-04-25  Jonathan Coles   <[email protected]>
3862    
3863            * Thuban/Model/proj.py (Projection.SetName): Set the name
3864            to "Unknown" if name is None.
3865            (Projection.SetAllParameters): New. Set the projection's
3866            parameter list to the one supplied.
3867            (Projection.SetProjection): New. Set the projection's
3868            properties to those of the supplied Projection.
3869    
3870            * Thuban/UI/mainwindow.py (MainWindow.MapProjection): Set
3871            the dialog title to include the map's title.
3872            (MainWindow.LayerProjection): Set the dialog title to include
3873            the layer's title.
3874    
3875            * Thuban/UI/projdialog.py (ProjFrame.__ShowError): Consolidate
3876            error dialogs into a single method call.
3877            (ProjFrame.__VerifyButtons): Add more states to check.
3878            (ProjFrame.__GetProjection): Return the current state of an
3879            edited projection or None.
3880            (ProjFrame.__FillAvailList): Remove checks for states that
3881            shouldn't exist.
3882            (ProjFrame._OnNew): Clear all selected items and supply
3883            a projection panel if necessary.
3884    
3885            * test/test_proj.py (TestProjFile.test): Add tests for
3886            ProjFile.SetAllParameters, ProjFile.SetProjection,
3887            ProjFile.SetName.
3888    
3889    2003-04-25  Jonathan Coles   <[email protected]>
3890    
3891            * Thuban/UI/projdialog.py (ProjFrame.__FillAvailList): Now
3892            takes an optional argument to select the current projection.
3893            This does not guarantee that the item is visible due to
3894            limited wxWindows functionality. Fixes RTBug #1821.
3895    
3896    2003-04-25  Jonathan Coles   <[email protected]>
3897    
3898            * Thuban/Model/load.py (SessionLoader.start_projection): Remember
3899            the projection name and use it when constructing the Projection
3900            object.
3901    
3902            * Thuban/Model/proj.py (Projection.__init__): Change the default
3903            value for 'name' to None and then test if name is equal to None
3904            in the body of the constructor. This way the caller doesn't have to
3905            know what the default value should be. Namely, useful in load.py
3906            where we have to pick a default value if the 'name' parameter
3907            doesn't exist in the XML file.
3908    
3909            * test/test_load.py (LoadSessionTest.testLayerProjection): New.
3910            Tests a file where a layer has a projection.
3911    
3912    2003-04-25  Jonathan Coles   <[email protected]>
3913    
3914            * Thuban/Model/layer.py (Layer.TreeInfo): Add an item to the
3915            tree for projection information.
3916    
3917            * Thuban/Model/load.py (XMLReader.GetFilename): Renamed from
3918            XMLReader.GetFileName.
3919            (SessionLoader): Added support for loading projection tags that
3920            appear inside a layer.
3921    
3922            * Thuban/Model/proj.py (ProjFile): Document the class. Move
3923            back to using a list because the order of the projections in
3924            the file is important to maintain. Fixes RTbug #1817.
3925    
3926            * Thuban/Model/resource.py: Rename calls to ProjFile.GetFileName
3927            to ProjFile.GetFilename.
3928    
3929            * Thuban/Model/save.py (SessionSaver.write_layer): Save projection
3930            information.
3931    
3932            * Thuban/UI/projdialog.py (ProjFrame._OnAddToList): Renamed from
3933            ProjFrame._OnSaveAs. Removed old dead code from previous
3934            implementation.
3935            (ProjFrame._OnExport): Add support for exporting more than one
3936            projection to a single file.
3937            (ProjFrame.__FillAvailList): use string formatting (% operator)
3938            to build strings that are (partly) translated. Fixes RTbug #1818.
3939    
3940            * test/test_proj.py (TestProjFile.test): New. Tests the base ProjFile
3941            class.
3942    
3943    2003-04-24  Bernhard Herzog  <[email protected]>
3944    
3945            * po/es.po: Updated Spanish translation by Daniel Calvelo Aros
3946    
3947            * po/fr.po: New. French translation by Daniel Calvelo Aros
3948    
3949            * Thuban/UI/projdialog.py (ProjFrame._OnSaveAs): Don't translate
3950            empty strings.
3951    
3952    2003-04-24  Jonathan Coles   <[email protected]>
3953    
3954            * Thuban/Model/layer.py (Layer.GetProjection): New. Needed to
3955            implement the interface that the ProjFrame dialog expects.
3956    
3957            * Thuban/Model/proj.py (Projection.SetName): New. Allows the
3958            name of the projection to be changed.
3959            (ProjFile): Use a dictionary instead of a list so that removing
3960            projections is easier and we are sure about uniqueness.
3961            (ProjFile.Remove): Remove the given projection object.
3962    
3963            * Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles):
3964            Return a list with only one projection file instead of searching for
3965            any projection file. This simplifies many things if the user can
3966            only have one system file and one user file.
3967    
3968            * Thuban/UI/classgen.py: Change all references to
3969            genCombo to genChoice.
3970    
3971            * Thuban/UI/mainwindow.py: Add a Projection option under the
3972            layer menu.
3973            (MainWindow.LayerProjection): New. Open up a projection window
3974            for a layer.
3975    
3976            * Thuban/UI/projdialog.py: Large changes to how the dialog is
3977            laid out. Use three panels instead of one. One for the list of
3978            projections, one for the edit controls, and one for the buttons.
3979            Fixed resizing problems so that the dialog resizes correctly
3980            when the projection panel changes. Added import/export, save, and
3981            new buttons/functionality.
3982    
3983    2003-04-24  Bernhard Herzog  <[email protected]>
3984    
3985            First step towards table management. Introduce a simple data
3986            abstraction so that we replace the data a layer uses more easily
3987            in the next step.
3988    
3989            * Thuban/Model/data.py: New file with a simple data abstraction
3990            that bundles shapefile and dbffile into one object.
3991    
3992            * Thuban/Model/session.py (Session.OpenShapefile): New method to
3993            open shapefiles and return a shape store object
3994    
3995            * Thuban/Model/layer.py (Layer.__init__): Pass the data as a store
3996            object instead of a shapefile filename. This introduces a new
3997            instance variable store holding the datastore. For intermediate
3998            backwards compatibility keep the old instance variables.
3999            (open_shapefile): Removed. No longer needed with the shape store.
4000            (Layer.SetShapeStore, Layer.ShapeStore): New methods to set and
4001            get the shape store used by a layer.
4002            (Layer.Destroy): No need to explicitly destroy the shapefile or
4003            table anymore.
4004    
4005            * Thuban/UI/mainwindow.py (MainWindow.AddLayer)
4006            (MainWindow.AddLayer): Use the session's OpenShapefile method to
4007            open shapefiles
4008    
4009            * Thuban/Model/load.py (ProcessSession.start_layer): Use the
4010            session's OpenShapefile method to open shapefiles
4011    
4012            * test/test_classification.py
4013            (TestClassification.test_classification): Use the session's
4014            OpenShapefile method to open shapefiles and build the filename in
4015            a more platform independed way
4016    
4017            * test/test_layer.py (TestLayer.setUp, TestLayer.tearDown):
4018            Implement to have a session to use in the tests
4019            (TestLayer.test_arc_layer, TestLayer.test_polygon_layer)
4020            (TestLayer.test_point_layer, TestLayer.test_empty_layer): Use the
4021            session's OpenShapefile method to open shapefiles
4022            (TestLayerLegend.setUp): Instantiate a session so that we can use
4023            it to open shapefiles.
4024            (TestLayerLegend.tearDown): Make sure that all references to
4025            layers and session are removed otherwise we may get a resource
4026            leak
4027    
4028            * test/test_map.py (TestMapAddLayer.test_add_layer)
4029            (TestMapWithContents.setUp): Instantiate a session so that we can
4030            use it to open shapefiles.
4031            (TestMapWithContents.tearDown): Make sure that all references to
4032            layers, maps and sessions are removed otherwise we may get a
4033            resource leak
4034            ("__main__"): use support.run_tests() so that more info about
4035            uncollected garbage is printed
4036    
4037            * test/test_save.py (SaveSessionTest.testSingleLayer): Use the
4038            session's OpenShapefile method to open shapefiles
4039            ("__main__"): use support.run_tests() so that more info about
4040            uncollected garbage is printed
4041    
4042            * test/test_selection.py (TestSelection.tearDown): Make sure that
4043            all references to the session and the selection are removed
4044            otherwise we may get a resource leak
4045            (TestSelection.get_layer): Instantiate a session so that we can
4046            use it to open shapefiles.
4047            ("__main__"): use support.run_tests() so that more info about

4049    
4050            * test/test_session.py (TestSessionBase.tearDown)
4051            (TestSessionWithContent.tearDown): Make sure that all references
4052            to the session and layers are removed otherwise we may get a
4053            resource leak
4054            (TestSessionWithContent.setUp): Use the session's OpenShapefile
4055            method to open shapefiles
4056    
4057    2003-04-24  Jonathan Coles   <[email protected]>
4058    
4059            * Thuban/Model/load.py (XMLReader.read): Should have been checking
4060            if the file_or_filename object had the 'read' attribute.
4061    
4062    2003-04-23  Jonathan Coles   <[email protected]>
4063    
4064            * Thuban/Model/resource.py: Fixes RTbug #1813.
4065            (ReadProjFile): Add documentation about which exceptions are raised.
4066            Always pass the exceptions up to the caller.
4067            (GetProjFiles): If the directory can't be read return an empty list.
4068            If any of the proj files can't be read skip that file and go
4069            on to the next one.
4070    
4071            * test/test_proj.py: Added test cases to handle nonexistent files,
4072            unreadable files, and files that don't parse correctly.
4073    
4074    2003-04-23  Jonathan Coles   <[email protected]>
4075    
4076            Projection dialog. Allows the user to select from a list
4077            of projection templates and optionally edit them and save new ones.
4078    
4079            * Thuban/UI/projdialog.py (ProjFrame): New. Main dialog.
4080            (ProjPanel): Base class for projection specific panels.
4081            (TMPanel): Projection panel for Transverse Mercartor.
4082            (UTMPanel): Projection panel for Universal Transverse Mercartor.
4083            (LCCPanel): Projection panel for Lambert Conic Conformal.
4084            (GeoPanel): Projetion panel for Geographic Projection.
4085    
4086    2003-04-23  Jonathan Coles   <[email protected]>
4087    
4088            * Thuban/Model/load.py (XMLReader): Renamed from XMLProcessor to
4089            promote symmetry. There now exists XMLReader and XMLWriter.
4090            (XMLReader.read): New. Call to read the given file descriptor or
4091            filename.
4092            (XMLReader.close): New. Make sure the file is closed.
4093            (XMLReader.GetFileName): New. Return just the file name that is being
4094            read from.
4095            (XMLReader.GetDirectory): New. Return just the directory of the file
4096            that is being read.
4097            (XMLReader.AddDispatchers): New. Take a dictionary which contains
4098            the names of functions to call as the XML tree is parsed.
4099            (XMLReader.startElementNS): Updated to use new dispatcher dictionary.
4100            (XMLReader.endElementNS): Updated to use new dispatcher dictionary.
4101            (SessionLoader): Removed class variables start_dispatcher and
4102            end_dispatcher since this functionality is now part of a class
4103            instance. Fixes RTbug #1808.
4104            (SessionLoader.__init__): Add dispatcher functions.
4105            (load_xmlfile): Code was moved into the XMLReader.read().
4106            (load_session): Use modified SessionLoader.
4107    
4108            * Thuban/Model/map.py (Map.GetProjection): New. Returns the
4109            map's projection.
4110    
4111            * Thuban/Model/proj.py (Projection.GetParameters): Renamed to
4112            GetAllParameters.
4113            (Projection.GetParameter): Returns the value for the given parameter.
4114    
4115            * Thuban/Model/resource.py: Use XMLReader and XMLWriter.

4121            list of ProjFile objects whose files are user defined.
4122            (ProjFileReader): Extend new XMLReader.
4123    
4124            * Thuban/Model/save.py (XMLWriter): Renamed from XMLSaver to
4125            promote symmetry.
4126    
4127            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Use a wxChoice
4128            control instead of a wxComboBox. wxChoice controls do not generate
4129            events as the uses highlights possible choices which fixes problems
4130            with resizing the dialog when the use selects an option.
4131    
4132            * Thuban/UI/classifier.py (Classifier.__init__): Use a wxChoice
4133            control instead of a wxComboBox.

4135            * Thuban/UI/mainwindow.py (MainWindow.Projection): Use new projection
4136            dialog.
4137

4139            method.
4140    
4141    2003-04-22  Bernhard Herzog  <[email protected]>
4142    
4143            * Thuban/UI/mainwindow.py: Remove some unused imports and global
4144            constants
4145    
4146            * Thuban/UI/identifyview.py (IdentifyListCtrl.selected_shape)
4147            (IdentifyGridCtrl.selected_shape): Use table, not shapetable.
4148    
4149    2003-04-17  Bernhard Herzog  <[email protected]>
4150    
4151            * Thuban/Model/layer.py: Don't import LAYER_LEGEND_CHANGED.
4152            (Layer): Update doc-string since LAYER_LEGEND_CHANGED is not used
4153            anymore.
4154            (Layer.BoundingBox, Layer.GetFieldType, Layer.NumShapes)
4155            (Layer.ShapeType, Layer.Shape): No need to call
4156            self.open_shapefile since it's always called in __init__
4157    
4158            * Thuban/UI/application.py (ThubanApplication.MainLoop): Removed.
4159            In wxPython 2.4 there's no need to extend MainLoop anymore since
4160            wxPython itself makes sure OnExit is called.
4161    
4162    2003-04-16  Jonathan Coles   <[email protected]>
4163    
4164            Initial putback of projection management code. Includes new
4165            classes to read and write projection files. The current load
4166            and save classes were abstracted a bit so they could be reused.
4167            The Projection class was extended to provide new methods and

4203            * extensions/thuban/wxproj.cpp (extract_projection)
4204            (extract_pointer): Rename extract_projection to extract_pointer
4205            and redefine its purpose to return the pointer stored in a CObject
4206            returned by the object's cobject method. Update all callers.
4207            (s_draw_info, free_draw_info, draw_polygon_init): Implement the
4208            handling of these low-level parameters so that each s_draw_info
4209            instance is handled as a CObject at python level that also
4210            contains real references to the actual python objects which
4211            contain the values in the struct. Add free_draw_info as the
4212            destructor.
4213            (draw_polygon_shape): Add the py_draw_info parameter which must a
4214            cobject containing an s_draw_info pointer.

4223            parameter.
4224    
4225    2003-04-15  Jonathan Coles   <[email protected]>
4226    
4227            * Thuban/Model/classification.py: Implemented __repr__ for

4236            save the group label.
4237

4243    
4244            * extensions/thuban/wxproj.cpp (draw_polygon_init): New. Used
4245            to improve rendering performance by initializing the variables
4246            that are not change each time draw_polygon_shape() is called.
4247            The values are stored in a global struct draw_info.
4248            (draw_polygon_shape): Removed initialization code that is
4249            now in draw_polygon_init().
4250

4308    
4309            * Resources/Bitmaps/dock_12.xpm, Resources/Bitmaps/undock_12.xpm:
4310            Updated design to try to make the button functionality more

4322            * Thuban/UI/classgen.py (ClassGenDialog.__init__): Actively
4323            set the current selections in the combo boxes. This is needed
4324            under Windows.
4325    
4326            * Thuban/UI/classifier.py (Classifier.__init__): Add a top
4327            level panel to the dialog so that the background colors are

4380    2003-04-10  Jonathan Coles   <[email protected]>
4381    
4382            * Thuban/Model/classification.py: (ClassGroupRange.__init__):
4383            Should pass group to ClassGroup constructor.
4384    
4385    2003-04-10  Jonathan Coles   <[email protected]>
4386    
4387            * Thuban/Model/classification.py: (ClassGroup): Move all the common
4388            methods of the derived classes ([Set|Get]Properties(), __eq__, __ne__)
4389            here. Implement SetVisible(), IsVisible().

4391            constructor.
4392    
4393            * Thuban/UI/classifier.py (ClassTable): Add a new column for the
4394            "Visible" check boxes.

4410    
4411            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
4412            draw visible groups.
4413    
4414    2003-04-09  Jonathan Coles   <[email protected]>

4416            * Thuban/UI/classgen.py: Modifications to allow simple
4417            addition and selection of new color schemes.
4418            (MonochromaticRamp): New. Generates a ramp between two colors.
4419            (RedRamp): New. Generates a ramp of all red.
4420            (GreenRamp): New. Generates a ramp of all green.
4421            (BlueRamp): New. Generates a ramp of all blue.
4422    
4423    2003-04-09  Jonathan Coles   <[email protected]>
4424    
4425            * Thuban/Model/classification.py (Classification.__deepcopy__):
4426            Need to copy over field and fieldType attributes.
4427    
4428            * Thuban/Model/table.py (Table.field_range): New. Retrive the
4429            maximum and minimum values over the entire table for a given
4430            field.
4431            (Table.GetUniqueValues): New. Retrieve all the unique values
4432            in the table for a given field.
4433    
4434            * Thuban/UI/classgen.py: Renamed GenRangePanel to GenUniformPanel.

4438            the user to select the properties for a custom ramp.
4439            (ClassGenerator.GenUniformDistribution): Was called GenerateRanges.
4440    
4441            * Thuban/UI/classifier.py: Removed a lot of debugging code.
4442            (Classifier._SetClassification): Callback method so that the
4443            class generator can set the classification in the grid.
4444            (ClassGroupPropertiesCtrl): New. Encapsulates the drawing and
4445            editing of a group properties class into a wxWindows control.
4446    
4447            * Thuban/UI/dock.py: It was decided that if the user closes
4448            a dockable window the window should simply hide itself. That
4449            way if the user wants to show the dock again it appears in the
4450            same place as it was when it was closed.
4451            (DockableWindow.Destroy): Call renamed method OnDockDestroy().
4452            (DockableWindow._OnButtonClose): Hide the window instead of

4465            to the map module
4466

4475            (MainWindow.ToggleLegend): New method to toggle visibility of the
4476            legend
4477            (MainWindow.ShowLegend): Implement in terms of ToggleLegend and

4479            (MainWindow.LegendShown): New method to return whether the legend
4480            is currently shown.
4481            (_method_command): Add checked parameter so we can define check
4482            menu items
4483            (_has_tree_window_shown, _has_legend_shown): Use the appropriate
4484            mainwindow methods.
4485            (show_session_tree, show_legend commands): Removed.
4486            (toggle_session_tree, toggle_legend commands): New commands to
4487            toggle the visibility of the dialogs
4488    
4489    2003-04-07  Jonathan Coles   <[email protected]>
4490    
4491            * Thuban/UI/classgen.py: Fix Windows problem.
4492    
4493            * Thuban/UI/dock.py: Fix Windows problem.
4494    
4495            * Thuban/UI/mainwindow.py: Use False instead of false.
4496            (MainWindow.ShowLegend): Remove unnecessary switch parameter.
4497    
4498    2003-04-07  Jonathan Coles   <[email protected]>
4499    
4500            Since we now say that the order of the groups in a classification
4501            matters, it makes sense to be able to manipulate that order. Most
4502            of the changes to Thuban/Model/classification.py are to that end.
4503    
4504            * Thuban/Model/classification.py (Classification.AppendGroup,
4505            Classification.InsertGroup, Classification.ReplaceGroup,
4506            Classification.RemoveGroup, Classification.GetGroup): Do as the
4507            names imply.
4508            (Classification.FindGroup): This was called GetGroup, but GetGroup
4509            takes an index, while FindGroup takes a value.
4510            (Classification.__deepcopy__): Copy all the groups, BUT NOT THE LAYER
4511            REFERENCE. Currently there is a cyclic reference between the layer
4512            and its classification. If the classification doesn't need to know
4513            its owning layer we can change this, since it may make sense to be
4514            able to use the same classification with different layers.
4515    
4516            * Thuban/Model/load.py: Use Classification.AppendGroup(), not AddGroup()
4517    
4518            * Thuban/UI/classgen.py: Use Classification.AppendGroup(),
4519            not AddGroup()
4520    
4521            * Thuban/UI/classifier.py: Now that we can depend on the order in
4522            a Classification and have methods to manipulate that order we don't
4523            need to use our own data structures in the grid. We can simply make
4524            the grid/table access the information they need from a copy of
4525            the classification object.
4526            (Classifier._OnCloseBtn): Event handler for when the user clicks
4527            'Close'. This is needed so if the user applies changes and then
4528            continues to change the table the user has the option of discarding
4529            the most recent changes and keeping what they applied.
4530    
4531            * Thuban/UI/mainwindow.py: Put "Show Legend" and "Show Session Tree"
4532            into the same group.
4533    
4534            * extensions/thuban/wxproj.cpp (check_version): If Thuban is compiled
4535            with a really old version of proj, PJ_VERSION won't even be defined.
4536            If it isn't defined then just compile so that the function always
4537            returns Py_False.
4538    
4539            * test/test_classification.py: Fix tests to use the renamed methods.
4540            Still need to write tests for the new methods.
4541    
4542    2003-04-04  Jonathan Coles   <[email protected]>
4543    
4544            * Thuban/UI/classifier.py (Classifier.__SelectField): Move the
4545            call to SetSelection out of the method and before the call
4546            to __SelectField in __init__. This prevents a recursion of events

4686            (MainWindow.ShowLegend): Show the legend docked by default.
4687    
4688    2003-03-28  Jonathan Coles   <[email protected]>

4694    
4695            * Thuban/UI/dock.py: Complete rework on the dock code so that
4696            that it is fairly removed from the rest of the Thuban application.
4697            It is easy to add new docks which the rest of the program having
4698            to be aware of them.
4699    
4700            * Thuban/UI/legend.py: Modifications to support selecting a

4719    
4720    2003-03-26  Jonathan Coles   <[email protected]>
4721    
4722            This putback contains the code for dockable windows. There is
4723            no support in wxWindows as of this date for windows that can
4724            attach themselves to other windows.
4725    
4726            The current model contains a DockableWindow which has a parent
4727            window for when it is detached and a dock window that it puts
4728            its contents in when it is docked. The contents of a DockableWindow
4729            must be a DockPanel. DockPanel itself derives from wxPanel.
4730    
4731            * Thuban/Model/layer.py (Layer.ClassChanged): Send a LAYER_CHANGED
4732            message, not a LAYER_LEGEND_CHANGED message.

4734            * Thuban/Model/map.py (Map): Forward LAYER_CHANGED messages.
4735    
4736            * Thuban/UI/classifier.py (Classifier.__init__): Use wxADJUST_MINSIZE
4737            as one of the style properties for the fieldTypeText item to
4738            be sure that its size is correct when the text changes.
4739    
4740            * Thuban/UI/dock.py: New. Classes for the DockPanel and
4741            DockableWindow.
4742    
4743            * Thuban/UI/legend.py: Added some more buttons and made the
4744            LegendPanel a DockPanel.
4745    
4746            * Thuban/UI/mainwindow.py: Added sash windows to the main window
4747            and supporting functions for manipulating the sashes.
4748            (MainWindow.ShowLegend): Create a DockableWindow with the
4749            LegendPanel as the contents.
4750    
4751            * Thuban/UI/messages.py: Added DOCKABLE_* messages
4752    
4753            * Thuban/UI/view.py (MapCanves.SetMap): Listen for LAYER_CHANGED,
4754            not LAYER_LEGEND_CHANGED, messages.
4755    
4756    2003-03-25  Jonathan Coles   <[email protected]>
4757    
4758            * setup.py: Added custom script bdist_rpm_build_script so that
4759            when the rpm is built the path to wx-config is correct.
4760    
4761            * setup.cfg: Added line saying to use the custom build script
4762    
4763    2003-03-20  Jonathan Coles   <[email protected]>
4764    
4765            Initial implementation of the Legend.
4766    
4767            * Thuban/UI/legend.py: New. Creates a window that shows the map's
4768            Legend information and allows the user to add/modify classifications
4769            and how the layers are drawn on the map.
4770    
4771            * setup.py: New command 'build_docs' which currently uses
4772            happydoc to generate html documentation for Thuban.
4773    
4774            * Thuban/Model/classification.py (ClassGroup.GetDisplayText): New.
4775            Returns a string which is appropriately describes the group.

4781            specific, messages.
4782    
4783            * Thuban/Model/messages.py: New message to indicate that a layer's
4784            data has changed (LAYER_CHANGED). New map messages to indicate
4785            when layers have been added/removed/changed or if the stacking order
4786            of the layers has changed.
4787    
4788            * Thuban/Model/session.py: Rename and use new messages.
4789    
4790            * Thuban/UI/classifier.py: Remember if any changes have actually
4791            been applied so that if the dialog is cancelled without an application
4792            of changes we don't have to set a new classification.
4793            (ClassDataPreviewer): Pulled out the window specific code and put it
4794            ClassDataPreviewWindow. ClassDataPreviewer can then be used to draw
4795            symbols on any DC.
4796            
4797            * Thuban/UI/mainwindow.py: New code to open the legend.
4798    
4799            * Thuban/UI/view.py: Use new message names.
4800

4807            version against what wxproj was compiled with.
4808            (check_version_gtk): If wxproj was compiled with gtk then check
4809            the given version against the version of the gtk library
4810            currently being used.
4811    
4812    2003-03-14  Bernhard Herzog  <[email protected]>
4813    
4814            * test/test_command.py: Run the tests when the module is run as a
4815            script
4816    
4817    2003-03-14  Bernhard Herzog  <[email protected]>
4818    
4819            Implement selection of multiple selected shapes in the same layer:
4820    
4821            - Introduce a new class to hold the selection. This basically
4822              replaces the interactor which was nothing more than the
4823              selection anyway. A major difference is of course that the new
4824              selection class supports multiple selected shapes in one layer
4825            
4826            - Move the object that represents the selection from the
4827              application to the canvas. The canvas is a better place than the
4828              application because the selection represents which shapes and
4829              layer of the map displayed by the canvas are selected and
4830              affects how the map is drawn.
4831    
4832            - Make the selection and its messages publicly available through
4833              the mainwindow.
4834    
4835            - The non-modal dialogs do not get a reference to the interactor
4836              anymore as they can simply refer to their parent, the
4837              mainwindow, for the what the interactor had to offer.
4838    
4839            * Thuban/UI/selection.py: New module with a class to represent the
4840            selection.
4841    
4842            * Thuban/UI/messages.py (SELECTED_TABLE, SELECTED_MAP): Remove
4843            these unused messages
4844    
4845            * Thuban/UI/application.py (ThubanApplication.OnInit)
4846            (ThubanApplication.OnExit, ThubanApplication.SetSession): The
4847            interactor is gone now.
4848            (ThubanApplication.CreateMainWindow): There is no interactor
4849            anymore so we pass None as the interactor argument for now for
4850            compatibility.
4851    
4852            * Thuban/UI/view.py (MapCanvas.delegated_messages)
4853            (MapCanvas.Subscribe, MapCanvas.Unsubscribe): In Subscribe and
4854            Unsubscribe, delegate messages according to the delegated_messages
4855            class variable.

4857            attributes from instance variables as described with the
4858            delegated_methods class variable.
4859            (MapCanvas.__init__): New instance variable selection holding the
4860            current selection
4861            (MapCanvas.do_redraw): Deal with multiple selected shapes. Simply
4862            pass them on to the renderer
4863            (MapCanvas.SetMap): Clear the selection when a different map is
4864            selected.
4865            (MapCanvas.shape_selected): Simple force a complete redraw. The
4866            selection class now takes care of only issueing SHAPES_SELECTED
4867            messages when the set of selected shapes actually does change.
4868            (MapCanvas.SelectShapeAt): The selection is now managed in
4869            self.selection
4870    
4871            * Thuban/UI/mainwindow.py (MainWindow.delegated_messages)
4872            (MainWindow.Subscribe, MainWindow.Unsubscribe): In Subscribe and
4873            Unsubscribe, delegate messages according to the delegated_messages

4876            attributes from instance variables as described with the
4877            delegated_methods class variable.
4878            (MainWindow.__init__): The interactor as ivar is gone. The
4879            parameter is still there for compatibility. The selection messages
4880            now come from the canvas.
4881            (MainWindow.current_layer, MainWindow.has_selected_layer):
4882            Delegate to the the canvas.
4883            (MainWindow.LayerShowTable, MainWindow.Classify)
4884            (MainWindow.identify_view_on_demand): The dialogs don't need the
4885            interactor parameter anymore.
4886    
4887            * Thuban/UI/tableview.py (TableFrame.__init__)
4888            (LayerTableFrame.__init__, LayerTableFrame.OnClose)
4889            (LayerTableFrame.row_selected): The interactor is gone. It's job
4890            from the dialog's point of view is now done by the mainwindow,
4891            i.e. the parent. Subscribe to SHAPES_SELECTED instead
4892            of SELECTED_SHAPE
4893            
4894            * Thuban/UI/dialogs.py (NonModalDialog.__init__): The interactor
4895            is gone. It's job from the dialog's point of view is now done by

4897            
4898            * Thuban/UI/classifier.py (Classifier.__init__): The interactor is
4899            gone. It's job from the dialog's point of view is now done by the
4900            mainwindow, i.e. the parent.
4901    
4902            * Thuban/UI/tree.py (SessionTreeView.__init__): The interactor is
4903            gone. It's job from the dialog's point of view is now done by the
4904            mainwindow, i.e. the parent.
4905            (SessionTreeCtrl.__init__): New parameter mainwindow which is
4906            stored as self.mainwindow. The mainwindow is need so that the tree
4907            can still subscribe to the selection messages.
4908            (SessionTreeCtrl.__init__, SessionTreeCtrl.unsubscribe_all)
4909            (SessionTreeCtrl.update_tree, SessionTreeCtrl.OnSelChanged): The
4910            selection is now accessible through the mainwindow. Subscribe to
4911            SHAPES_SELECTED instead of SELECTED_SHAPE
4912    
4913            * Thuban/UI/identifyview.py (IdentifyView.__init__): Use the
4914            SHAPES_SELECTED message now.
4915            (IdentifyView.selected_shape): Now subscribed to SHAPES_SELECTED,
4916            so deal with multiple shapes
4917            (IdentifyView.__init__, IdentifyView.OnClose): The interactor is
4918            gone. It's job from the dialog's point of view is now done by the
4919            mainwindow, i.e. the parent.
4920    
4921            * Thuban/UI/controls.py (RecordListCtrl.fill_list): The second
4922            parameter is now a list of shape ids.
4923            (RecordTable.SetTable): The second parameter is now a list of
4924            indices.
4925    
4926            * Thuban/UI/renderer.py (ScreenRenderer.RenderMap): Rename the
4927            selected_shape parameter and ivar to selected_shapes. It's now a
4928            list of shape ids.
4929            (MapRenderer.draw_label_layer): Deal with multiple selected
4930            shapes. Rearrange the code a bit so that the setup and shape type
4931            distinctions are only executed once.
4932    
4933            * test/test_selection.py: Test cases for the selection class
4934    
4935    2003-03-11  Jonathan Coles   <[email protected]>
4936    
4937            * Thuban/Model/load.py: Temporary fix so that the xml reader
4938            doesn't cause Thuban to crash.
4939    
4940            * Thuban/Model/layer.py: Handle the cyclic references between
4941            a layer and its classification better, and be sure to disconnect
4942            the classification from the layer when the layer is destroyed
4943            so that we don't maintain a cyclic reference that may not be
4944            garbage collected.
4945    
4946            * Thuban/Model/classification.py: See comment for layer.py.
4947    
4948    2003-03-12  Jan-Oliver Wagner <[email protected]>
4949    
4950            * HOWTO-Release: New. Information on the steps for releasing
4951            a new version of Thuban.
4952    
4953    2003-03-11  Jonathan Coles   <[email protected]>
4954    
4955            * Thuban/UI/classifier.py: Add normal border to SelectPropertiesDialog.
4956            Use True instead of true.
4957            (Classifier): Should have a single panel in which all the controls lie.
4958    
4959            * Thuban/UI/proj4dialog.py: Add normal border.
4960    
4961            * Thuban/UI/tree.py: Fixed problem with bad item images under Windows.
4962    
4963            * Thuban/UI/mainwindow.py: Use True instead of true.
4964    
4965            * setup.py: Update some definitions to use wxWindows2.4 files
4966    
4967            * Data/iceland_sample_class.thuban: Fixed file so that the
4968            field_type information is present.
4969    
4970    2003-03-10  Jonathan Coles   <[email protected]>
4971    
4972            * Thuban/UI/classifier.py (Classifier.__init__): Make the
4973            field type label grow so that when the text changes the
4974            size is updated correctly. This may be a wxWindows bug.
4975    
4976    2003-03-10  Jonathan Coles   <[email protected]>
4977    
4978            * Thuban/UI/application.py: Changed SESSION_CHANGED to
4979            SESSION_REPLACED.
4980    
4981            * Thuban/UI/classifier.py: Wrap text with _().
4982            (ClassGrid.CreateTable): Set dimensions and size hints here,
4983            instead of in Reset, so we only set the size once.
4984    
4985            * Thuban/UI/dialogs.py: Don't need Shutdown(); just use Close()!
4986    
4987            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
4988            Call Close() instead of Shutdown().
4989    
4990            * Thuban/UI/messages.py: Changed SESSION_CHANGED to SESSION_REPLACED.
4991    
4992            * Thuban/UI/tree.py: Changed SESSION_CHANGED to SESSION_REPLACED.
4993            Go back to using OnClose() instead of Shutdown().
4994    
4995    2003-03-10  Jonathan Coles   <[email protected]>
4996    
4997            * Thuban/UI/classifier.py (Classifier): SelectField() needed
4998            to know the old field index as well as the new one.
4999    
5000    2003-03-10  Jonathan Coles   <[email protected]>
5001    
5002            * Thuban/UI/classifier.py (Classifier): Use __SelectField()
5003            to correctly set the table information and call this from
5004            __init__ and from _OnFieldSelect so that all the information
5005            is up to date when the dialog opens and when a field is changed.
5006    
5007    2003-03-10  Jonathan Coles   <[email protected]>
5008    
5009            * Thuban/Model/classification.py (Classification): Don't use
5010            layer's message function directly, use the ClassChanged() method
5011            when then classification changes. SetField/SetFieldType/SetLayer
5012            must keep the information about field name and field type in
5013            sync when an owning layer is set or removed.
5014    
5015            * Thuban/Model/layer.py: Added ClassChanged() so that the
5016            classification can tell the layer when its data has changed.
5017            (Layer.SetClassification): Accepts None as an arguement to
5018            remove the current classification and correctly handles
5019            adding a new classification.
5020    
5021            * Thuban/Model/load.py: Comment out print statement
5022    
5023            * test/test_classification.py, test/test_save.py: New and
5024            improved tests.
5025    
5026    2003-03-07  Jonathan Coles   <[email protected]>
5027    
5028            * Thuban/Model/classification.py: Implemented __copy__ and
5029            __deepcopy__ for ClassGroup* and ClassGroupProperites so
5030            they can easily be copied by the classifier dialog.
5031            (ClassGroupProperites.__init__): The default line color should
5032            have been Color.Black.
5033    
5034            * Thuban/UI/classifier.py: Setting and Getting table values now
5035            uses a consistent set of functions.
5036            (Classifier): Now non-modal. Has field type label which changes
5037            as the field changes. Keep track of buttons in a list so that
5038            we can enable/disable the buttons when the None field is selected.
5039            (SelectPropertiesDialog): Add buttons to make the colors transparent.
5040    
5041            * Thuban/UI/dialogs.py (NonModalDialog.Shutdown): New method which
5042            does what OnClose did, but can be called by the application to
5043            close a window. Needed when a session changes, and we have to
5044            close the classifier windows.
5045    
5046            * Thuban/UI/mainwindow.py (MainWindow.prepare_new_session):
5047            Shuts down open dialogs. Used when a new session is created
5048            or a session is opened.
5049            (MainWindow.SaveSession): Should only call application.SaveSession()
5050            if we don't call SaveSessionAs first.
5051            (MainWindow.Classify): Allow different classifier dialogs for
5052            different layers.
5053    
5054            * Thuban/UI/tree.py (SessionTreeView): Remove OnClose and let
5055            the parent class handle it. Add Shutdown() to unsubscibe from
5056            event notification and call the parent Shutdown(). This was
5057            necessary so the application can close the tree window.
5058    
5059    2003-03-06  Jonathan Coles   <[email protected]>
5060    
5061            * Thuban/Model/classification.py: Minor documentation changes,
5062            Addition of __eq__ and __ne__ methods.
5063            (Classification.SetLayer): prevent recursion between this method
5064            and Layer.SetClassification().
5065    
5066            * Thuban/Model/color.py: Addition of __eq__ and __ne__ methods.
5067    
5068            * Thuban/Model/layer.py (SetClassification): prevent recursion
5069            between this method and Classification.SetLayer().
5070    
5071            * test/test_classification.py, test/test_load.py,
5072            test/test_session.py: Fixed and added tests for the classification
5073            classes.
5074    
5075    2003-03-06  Bernhard Herzog  <[email protected]>
5076    
5077            * Thuban/UI/classifier.py (ClassGrid.__init__)
5078            (ClassGrid.CreateTable): Move the SetSelectionMode call to
5079            CreateTable because otherwise it triggers an assertion in
5080            wxPython/wxGTK 2.4.
5081    
5082    2003-03-05  Jonathan Coles   <[email protected]>
5083    
5084            * Thuban/common.py: Move FIELDTYPE constants back to table.py.
5085    
5086            * Thuban/Model/load.py: import FIELDTYPE constants from table.
5087    
5088            * Thuban/UI/classifier.py: import FIELDTYPE constants from table.
5089    
5090            * Thuban/Model/table.py: Put FIELDTYPE constants back.
5091    
5092    2003-03-05  Jonathan Coles   <[email protected]>
5093    
5094            * Thuban/UI/classifier.py: Added class documentation.
5095            Fixed RTbug #1713, #1714. Added Move[Up|Down] buttons.
5096            Store just the groups in the table and generate the other
5097            column information when it is requested. Add "None" field
5098            to pull-down to select no classification.
5099    
5100            * Thuban/common.py: Moved FIELDTYPE constants from table.py
5101            (Str2Num): Only catch ValueError exceptions.
5102    
5103            * Thuban/Model/classification.py: Class documentation. Renaming
5104            of methods with Stroke to Line. Groups are stored in a single
5105            list with the default as the first element. Groups are searched
5106            in the order they appear in the list.
5107    
5108            * Thuban/Model/color.py: Documentation.
5109    
5110            * Thuban/Model/layer.py (Layer): Add GetFieldType to retreive
5111            the kind of data represented by a field.
5112    
5113            * Thuban/Model/load.py (ProcessSession): Use proper string
5114            conversion function; fixes RTbug #1713.
5115    
5116            * Thuban/Model/save.py (Saver): Store field type information.
5117    
5118            * Thuban/Model/table.py: Put FIELDTYPE constants in common.py.

5121    
5122            * Thuban/UI/mainwindow.py: Function name changes.
5123    
5124            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Only
5125            get the layer classification once. Don't try to classify
5126            values when the field is None: just use the default properties.
5127    
5128            * Thuban/UI/view.py: Function name changes.
5129    
5130            * Doc/thuban.dtd: Add field_type attribute to a classification.
5131    
5132    2003-03-04  Bernhard Herzog  <[email protected]>
5133    
5134            * Doc/thuban.dtd: Use correct syntax for optional attributes. Make
5135            the fill and stroke layer attributes optional with suitable
5136            default values. Add the stroke_width layer attribute. Use correct
5137            syntax for empty elements. Make the attribute list for labels
5138            refer to the label element.
5139    
5140    2003-03-04  Bernhard Herzog  <[email protected]>
5141    
5142            * setup.py (thuban_build_py.build): Add a comment about distutils in
5143            Python 2.3 containing some of the functionality we implement in
5144            setup.py ourselves.
5145    
5146            * Thuban/UI/classifier.py (ClassGrid.__init__): Set the table
5147            before the selection mode. Doing it the other way round triggers
5148            an assertion in wxWindows.
5149    
5150            * Thuban/Model/save.py (escape): Fix typo in doc-string
5151    
5152            * Thuban/Model/classification.py: Remove unnecessary wxPython
5153            import

5158            Parameter 'value' should default to None.
5159    
5160            * Thuban/UI/mainwindow.py: Use Layer.GetClassification() since
5161            the class attribute __classification is now private.
5162    
5163            * Thuban/UI/classifier.py (ClassGrid): Moved OnCellDClick() from
5164            Classifier to ClassGrid. Added support for removing selected rows,
5165            which including code for keeping track of when cells are selected,
5166            and deselected.
5167            (ClassTable): Support for added/removing rows. Fixed a problem
5168            with __ParseInput whereby it would not allow strings (only numbers)
5169            to be entered.
5170            (Classifier): Added button and supporting code for removing
5171            selected rows.
5172    
5173    2003-02-27  Jonathan Coles   <[email protected]>
5174    
5175            * Thuban/common.py: Moved color conversion functions into
5176            Thuban/UI/common.py.
5177            (Str2Num): Now converts the float (not the string) to a long/int
5178            so that an exception isn't thrown.
5179    
5180            * Thuban/UI/common.py: Common functions used in several UI modules
5181    
5182            * Thuban/Model/classification.py: Changed the class hierarchy
5183            so that a Classification consists of Groups which return
5184            Properties when a value matches a Group.
5185    
5186            * Thuban/Model/layer.py: Fixed name resolution problem.
5187    
5188            * Thuban/Model/load.py: Use new Classification and Group functions.
5189    
5190            * Thuban/Model/save.py (Saver.write_attribs): Fixes a test case
5191            failure.
5192            (Saver.write_classification): Use new Classification and Group
5193            functions.
5194    
5195            * Thuban/UI/classifier.py: Changes to use new Classification and Group
5196            functions. Fix to create a tuple with a single value instead of
5197            simply returning the value.
5198    
5199            * Thuban/UI/renderer.py: Use new Classification and Group functions.
5200            Use common.py functions.

5223            changes.
5224    
5225            * Thuban/UI/mainwindow.py (MainWindow.OpenSession,
5226            MainWindow.SaveSessionAs): Text string changes so the dialogs
5227            have more meaningful titles.
5228    
5229            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Change
5230            Classification method name from GetProperties to GetClassData.
5231    
5232            * Thuban/UI/view.py (MapCanvas.find_shape_at): Use method calls
5233            instead of accessing now non-existent class variables.
5234

5236    
5237            * Thuban/UI/renderer.py (MapRenderer.draw_shape_layer): Remove
5238            unneeded Shape() call. Rendering is substantially faster without
5239            it and it avoids some problems with broken shape files.
5240    
5241    2003-02-20  Frank Koormann   <[email protected]>
5242    
5243            Force minimal size of identify and label dialogs. The autosizing
5244            looked too ugly.
5245    
5246            * Thuban/UI/controls.py (RecordListCtrl): Set minimal width for columns.
5247            * Thuban/UI/labeldialog.py (LabelDialog.dialog_layout):

5268    
5269            * Thuban/Model/color.py: Added Color.None to represent something
5270            with no color. Color.Black represents the color black.
5271            (NoColor): Helper class derived from Color to represent something
5272            with no color.
5273    
5274            * Thuban/Model/layer.py (Layer): Removed references to fill, stroke,
5275            stroke_width attributes. Made the 'classification' attribute private.
5276            New methods for setting/getting the classification.
5277    
5278            * Thuban/Model/load.py (ProcessSession): Use new methods on Layer
5279            to get the classifcation and use the new ClassData* classes to
5280            hold the classification data. Use Str2Num to convert numbers
5281            properly.
5282    
5283            * Thuban/Model/save.py (Saver): Use new Color and Classification
5284            methods
5285

5295            (ClassPreviewer): Took the Draw method from ClassRenderer and
5296            made most of it into this new class. Intend to use this class in
5297            the SelectPropertiesDialog for previewing changes.
5298    
5299            * Thuban/UI/renderer.py: Use new Color and Classification methods.
5300

5336    
5337            * Thuban/Model/save.py (Saver.open_element, Saver.close_element):
5338            Added element_open variable to track opening and closing of tags

5348    
5349            * Thuban/Model/layer.py (Layer): Remove the

5378            Layer.SetStrokeWidth): Modified these functions to change the
5379            null data in the classification rather than keep these values
5380            directly in the Layer class. Menu options to change these values
5381            work again.
5382

5384    
5385            * Thuban/UI/classifier.py (Classifier): Resolved merging conflicts.

5685    
5686            * Thuban/Model/save.py (Saver): New class to handle serializing a
5687            session into an XML file. The main reason to introduce a class is

5690            (save_session): Delegate almost all the work to the Saver class.
5691            Rename the filename argument to file because it may be a file like
5692            object now.
5693    
5694            * Thuban/Model/load.py: Get rid of the Python 1.5.2 compatibility
5695            code. Remove the little test code which would be executed when the
5696            module is run as a script which didn't work anymore since it can't
5697            import the other Thuban modules.
5698            (ProcessSession, load_session): Refactor the ProcessSession to
5699            have one method for each element start and end tag so that derived
5700            classes can easily override the processing of individual tags.
5701            Also, always parse with namespaces enabled because applications
5702            built on top of Thuban will likely use namespaces if they extend
5703            the session file format.
